About Google Calendar

Google Calendar is a free time-management web application offered by Google. It became available on April 13, 2006, and exited the beta stage in July 2009. Users are required to have a Google Account in order to use the software.

The interface of Google Calendar, designed by Kevin Fox (who also designed Gmail and the second version of Google Reader), is similar to desktop calendar applications such as Microsoft Outlook or iCal on Mac OS X. The Ajax-driven interface enables users to view, add, and drag-and-drop events from one date to another without reloading the page. It supports view modes such as weekly, monthly, and agenda. Users can "quick add" calendar events by typing standard English phrases, such as "Dinner with Michael 7 p.m. tomorrow". Users can also set the number of days to show in their custom view mode.

Events are stored online; consequently, the calendar can be viewed from any location that has Internet access. For users who might experience a hard drive failure, it also means that no data is lost. The application can import Microsoft Outlook calendar files (.csv) and iCalendar files (.ics, the de facto open calendaring file format). Multiple calendars can be added and shared, allowing various levels of permissions for the users. This enables collaboration and sharing of schedules amongst groups. General calendars available for importing into one's account include those containing national holidays of various countries. Users can also add "live" iCalendar URLs that update regularly.

Google Calendar allows multiple calendars to be created and shown in the same view. Each can be shared, either read-only or with full edit control, and either with specified people or with everyone (public calendars). In February 2009, Google discontinued the option of searching for public calendars from the search field by removing the "Search Public Events" button. It also disabled its public calendar gallery, citing maintenance and usability issues. The company suggests adding calendars via the "Interesting Calendars" feature, known calendar URLs, or via email requests to friends. Daily "To Do" tasks cannot currently be shared between users.

Currently, Google Calendar can use Google Sync to synchronize with many mobile devices (e.g., BlackBerry, Palm, iPhone, Pocket PC) or with PC applications (e.g., Microsoft Outlook) via third party software, and natively with Apple's iCal (workarounds required for iCal 3.x, full functionality with iCal 4.x). Google Calendar is natively supported on Android-based mobile phones such as the T-Mobile G1 and the Motorola CLIQ and on webOS-based mobile phones such as the Palm Pre and Palm Pixi. Event reminders can be sent via email, as well as via SMS to mobile phones in more than eighty countries and regions.

  • I love that an app I use so often works so well. I must open the app 20 times a day, at a bare minimum. Google knew what they were doing when they designed this calendar app. The flat design and easiness to navigate puts it at the top of my charts everyday.

    Pros : Great user interface. Attractive flat surface design. Always synced up. New cool task/reminder feature

    Cons : I can't see calendar notes in the list view. But that's no deal breaker for me.

  • For Android users, Google Calendar is a powerful system that can synchronize your event-driven life among all of your devices without pressing a single button. From the comfort of your office chair, you can set up your weekly agenda which is then immediately shared with your phone and tablet at home. As the system is free to use, it can be quite an asset for business applications and sharing information is as easy as adding an email address of the person you want to share with.

  • What do you like best?

    Easy to add calendar-sharing with individuals and co-workers

    What do you dislike?

    Not easily viewable / integratable to Outlook

    Google Calendar is a solid way to manage your daily activities, the user interface is really simple and easy to use. Now that I have a while using it I think is a good choice to organize your tasks, I currently use it to share my "online hours" with my team so they can come to my calendar and check it out to see if I'm available.

    Pros :

    These are some of the things that I like about Google Calendar:

    • UX/UI: It's very intuitive, you can visit the calendar for the first time, and you'll automatically understand how it works (Of course it's made by Google). Some of the features that I like the most about UX is the fact of using drag and drop to organize your activities or tasks.
    • Sharing: You can share your calendar with other people and honestly this is the feature that I like the most along the site because everybody (that you want) will be able to see what you're doing without asking you. I work with teams and believe me, this is priceless. Also, when you see calendars from others, you can assign a color to each one in order to make it more organized.
    • Made by Google: This means that you have the advantage of using calendar with other tools from Google, which is great.

    Cons :

    Here a couple of things I think Google Calendar can do better:

    • Calendar's sharing design: When other people is sharing their calendars with you, your board can get a little bit messed up because of the quantity of elements that have activities on the same days, this is something annoying because it's difficult to find something specific when you have those many elements in the same boxes.

    All Google products and applications demonstrate every times to be simple, effective, and performing dynamic and attractive. Google calendar is one of them, play fully its role, is a great calendar and stands for innovation, design and great potential.

    Pros :

    • Among the various features, I believe that the most useful is the ability to share calendars with other people, you can then view the events of every contact with whom you have shared calendar, this avoids continually postpone the same proposal of meeting or event.
    • About your contacts, you can find them easily integrated with your address book tied to your Google account.
    • Calendar also integrates with Gmail, Drive, Contacts, Sites, and Hangouts.
    • You can also do a migration of your enterprise calendar (for example, Exchange, Outlook, or by exporting directly of .ics or .csv file.
    • About alerts, Calendar includes a notification via a popup pop-up which will warn you ten minutes before an event.
    • The default time interval of 10 min is obviously changeable between your reminder settings.
    • Reminders can also enter directly from the calendar.
    • Calendar includes an excellent integration with maps, and you can easily find a place for an appointment with a few clicks.
    • It automatically syncs with your email account.
    • The application is very stable and is compatible with most of the smartphones on the market.
    • Very convenient widget, although not available for all types of smartphones.
    • In the latest version Google have made several improvements, they also added a large number of languages ​​(30 different languages), they added the "holidays" to the majority of countries, they added the option to delete an appointment without necessarily entering the modification thereof.

    Cons :

    • It is not allowed to go to change or add to the birthday notifications synchronized through Google contacts. You will find it on the calendar, but will not warn you when a birthday is coming up, and you'll have to check it every time by yourself.
    • You can not copy events from one day to another, you can only move the schedule from day to day.

    Google calendar is one app, which many of us use it unknowingly. It syncs directly with the connected Facebook events. The early morning notification of your friend's birthday is none other than from the Google calendar. It has quite enough features which make it better than its competitors. It has tight integration with Gmail. Gmail is one of the widely used email services over the globe. Its integration helps one to sync even the travel dates and the hotel stay dates with the calendar. You will get enough reminder of the same. All of the calendar events in Gmail can now get synced with the Google Calendar.

    Pros :

    • There are many interesting features in Google Calendar.
    • One of such feature is the auto decline feature.With this feature, you can quickly decline all of the scheduled meetings. One can also attach Google Document to the Google Calendar. So one need not explain in detail about the meeting. They can simply attach the document to the Google Calendar, and the user will download and refer the same.
    • The interface of Google Calendar is similar to desktop calendar application such as Microsoft Calendar.
    • One can sync the Google Calendar information in Phone, tablet and desktop. Same piece of events would be available across the devices, which allows us to keep in sync. The suggested Time feature of Google Calendar suggests a time when the meeting can be held, based on the availability of the participants.
    • There is another feature Find a time, wherein all the participants schedule can be seen side by side.
    • One needs to identify the time wherein all of the participants are free.
    • One can also add Google Hangout or Video to the Google Calendar.

    Cons :

    • The Reminders which are set sometimes pops up and kind of create nuisances and annoying.
    • One may need to close or exit the same.

    Google Calendar is that tool that will make you will hear me say “it’s on my agenda”. Long time ago, I stopped using physical agendas (And don’t know why some people still do) and started using Outlook, then the PST files backup process made me want to get out, I mean, why in the earth I have to stick with a file that is sealed in a computer being able to have it in the cloud and see my calendar with all my appointments on my computer, tablet or smartphone! And since the last update of the mobile app, I stopped using business calendar app, to use the native Android one. Google calendar has a good sync capability with many project management apps out there like Asana or Wrike, making it even better to help me navigate my busy days. When I have a meeting, I always ask for their email and immediately add them to the event. Also discovered the options of “suggest a time and find a time” that, as their names say, propose times to meet in your busy schedules. If you are on mobile, and don’t have data connection, you still can see your events and appoint new ones that will sync as soon as you get connected. When you create an event, and you set a location that matches a map location, it works with google maps to give you an easy to use the link so you can use it to navigate toward that destination. I really like the ability to create shared calendars in a way that I can create a new event and immediately it's visible to all the team members. Also, I use the “all day” events to remind me important things like bills to pay, family events, etc.

    Pros :

    • Awesome mobile integration.
    • Easy to collaborate with other google users.
    • Great access to see a list of events, daily or weekly view.
    • Fast event creations (can use quick add for even faster).

    Cons :

    • I think the interface can be worked to offer a more modern look.

    Google Calendar is much more than just a calendar - it can be used for task management, event planning, appointment management, timetables and collaboration. I have used many calendar and organiser applications throughout the years, and Google Calendar always stands out from the rest, and is surely the best all-rounder and a truly indispensable tool for freelancers, students, employers and employees alike. First of all, Google calendar can be accessed from anywhere, as long as an internet connection is present. This includes laptops, desktop computers, Macs, iPhones and Android devices. While the iPhone app does not perform in a manner as optimised as it's Android equivalent, all of them get the job done, and are excellent for users on the go.

    All platforms allow the quick addition of events, with the desired date, time and description being the main fields which are required. Google Calendar is ultimately excellent for appointment planning, however, it is also an excellent tool for scheduling and timetables, which makes it ideal for students and business users. Reminders and alerts can be setup, so that appointments and tasks are never missed. In fact, it is also possible to integrate Google Calendars with a Google Tasks account, so that to-do list tasks can appear within the user's calendar. In the same way, thousands of software applications also integrate with Google Calendar, so its usage is widespread and varied. Event planning is also a suitable task for Google Calendar since users can be invited to collaborate on events, which would appear in their calendar too. The disadvantage with this is that collaborating with users who do not use Google Calendar is not straightforward to get working.

    Google Calendar is, therefore, an excellent organisational tool, however, a standalone to-do list application might be more suitable for users looking for something more simple which does not involve specific times for events or tasks.

    Pros :

    • Mobile apps available.
    • Ability to collaborate with other users.
    • Can be used for scheduling and timetables.
    • Great for appointments.
    • Integration with Google Tasks.
    • Easy to view a summary of daily or weekly agenda.
    • Events can be added very quickly.
    • Can access from anywhere.
    • Alerts and reminders.
    • Thousands of software applications integrate with Google Calendar.

    Cons :

    • iPhone application does not perform as well as the Android equivalent.
    • For simple tasks which are not bound by dates, a simple to-do list application is better.
    • Sharing events with non-Google Calendar users is not easy.

    Google Calendar is a practical time management application which has the benefit of integration with other Google services such as Google Drive, Gmail, and Hangouts. It's intuitive, easy to use and has practical file sharing options. You can automate Google Calendar to remind you of appointments by mail or by direct notification to your phone, which makes sure you will not miss an appointment. Another important feature of this application is that it has excellent integration across devices. For instance, you can synchronize Google Calendar with your smartphone, and any changes you make from a desktop or laptop computer will be reflected immediately. Google Calendar also simplifies teamwork, since you can share your calendar with collaborators– if someone invites you to an appointment, he or she will immediately know if you are available at the proposed hour.

    Pros :

    • Google calendar has a clean interface and is free from ads. It is also light on system resources, being a web application. Appointment management is simplified because events can be dragged around to change their hour and date, and they can be stretched or shortened to adjust duration.
    • When meetings are scheduled across time zones over the Internet, Google Calendar automatically converts the hours to the corresponding time zone each participant. Also, you can create an event based on a different time zone to adapt to the availability of another collaborator, and then it is automatically converted to yours.
    • Communication is greatly enhanced thanks to Gmail integration, and file sharing benefits from Google Drive integration.
    • Sharing your calendar with collaborators greatly reduces correspondence to determine participant availability. With overlapping calendars, it is much simpler to schedule a meeting.

    Cons :

    • Probably the only drawback is that the smartphone version is limited in terms of options and accessibility, but this is not a drastic issue– it is simply a matter of opening the web app on a laptop computer or desktop.

    I think that Calendar is an under-appreciated application. Not only serves the purpose of organising the day, by creating meetings but its features empower what you usually expect from a calendar found in Outlook or any other mail client. And its integration with several other services makes it a great companion to the daily tasks.

    Pros :

    The features that I like the most:

    • Create time-zone related invites, everybody sees the meeting in their time zones and you can even create ones using a different time zone than your local one.
    • Integration with Google Hangouts. If you activate it, for every calendar you have your own hangout prepared for you to use. Great alternative to other services.
    • Document sharing. You can attach documents to the people invited can go with some work done or place the meeting summary right then and there.
    • Share your calendar with other people so they don't bother you asking "do you have time?...". And have a fair level of configuration around that. - Mark someone in the list as "optional", this is helpful when you want to communicate to him that is only to keep him in the loop.
    • Seamless integration with Google Mail, you can answer the RSVP directly from your inbox without even accessing to the email. And the two that I like the most:  Reserve Rooms. You can configure the meeting rooms you have in your offices and have them specified in the meeting invite. I think that you can also configure other resources too, but not so sure about that. Every meeting room has its own calendar so if other reserved there before you, it will reject it or not shown in the list.
    • Find a Time. It's call suggested times and what it does it finds other open slots where everyone has an open time at the same time. This is great when coordinating a meeting with several people in it.

    Cons :

    I can't think of too many since for me solved a lot of problems we had. If I have to be picky, I would say that I'd like to have more branding to the app, like with the Mail. Add themes or a company branding (other than putting the company logo) would be great.

    I've used Google Calendar for years. It's great because you can access it from and while logged into Gmail and it syncs across devices. It's also really easy to use. From within Gmail now, you can click on a date and time and it adds it to your calendar. You can also set up different calendars, say Personal, Business, Birthdays, Events etc. You can also invite people to a calendar appointment, like a business meeting for example. It has convenient fields for location, reminders you can set and you can even tell it to add a video call link, through Google Hangouts. There's even time zone conversion built-in, a very handy feature. It even syncs with iCal and other calendar systems. You can even use other systems to add appointments to Google Calendar. Gone are the days of calendars with pictures at the top that cost money. Google Calendar is no-nonsense and free. There's not even any ads in it.

    Pros :

    • Free (unless its part of the business plan which you pay monthly per user for a bunch of Google apps together like Gmail).
    • Easy to use.
    • No ads.
    • Integrates with Gmail.
    • Syncs with other calendar systems.

    Cons :

    None that I can think of.

    I can't remember the last time I purchased a physical calendar. You won't need one if you use Google Calendar. It’s perfect for type A people who want a super organized way to view their upcoming schedule and a great way to keep friends, family or colleagues up to date on appointments.

    Pros :

    What I love most about Google Calender is that it allows you to easily collaborate with others. You can share your Google calendar with other people so that they can see your appointments and you can invite people to specific events. It’s super easy to add appointments. You give them a title, date, time, location and description. You can even add attachments and assign them a specific color to differentiate them from your other events. You can set them up as one-time events or repeating. And you can create notifications so that you’ll get an email when the event is approaching. It’s at this time that you can add invite emails, or even attachments, and then go back later to see the guest list. Many businesses use Google Calendar, meaning that if you book an appointment, flight or a restaurant reservation, or even want to set a reminder to order a dish through UberEATS, you can easily add it to your Google Calendar when you get an email confirmation of your appointment or a notice about an upcoming event. As always, you can add in appointments manually, but it’s nice that it’s becoming more common to see Google Calendar integrated into marketing. I also like that you can switch from a monthly to weekly view and even to an agenda that shows you your upcoming events in more of a list format, rather than a calendar style. You can also easily print any of these pages. And of course, you can sync your calendar with your mobile device, so your detailed calendar is always with you.

    Cons :

    Your workplace likely will use Microsoft Outlook's calendar or another email platform's calendar more often than Google Calendar, but it's still great for your personal appointments!

    Google Calendar is probably the simplest cloud calendar application to use. It works with iOS and Android. It's easy to share as well.

    Pros : Free and works everywhere

    Cons : CalDAV sync is so so.
