Google Calendar is a time-management and scheduling calendar service developed by Google. It became available as a limited beta release on April 13, 2006,[3] and exited the beta stage in July 2009.[4] It is available as a web application and as mobile apps for the Android[5] and iOS[6] mobile operating systems.


Google Calendar allows users to create and edit events. Events have a set start time and stop time, with an option for an "All-day event". Users can enable a "Recurring" functionality with optional parameters for frequency. Users can add a color to an event for recognition or to distinguish the event from others. Users can optionally set notifications, with options for type (email, mobile push notification) and time. Locations can be added for easy understanding of an event's place. Events are viewable in different types of setups, including day, week, month, or schedule. Users can invite other people to events; for other Google Calendar users, the event becomes visible in their calendar, and for non-Google Calendar users, an email will have options for "Yes", "No", or "Maybe". Privacy settings allow the user to define the levels of public visibility of the entire calendar or individual events. Although the calendar defaults to showing users event times in their local time, users can specify a different time zone for an event. Users can enable or disable the visibility of special calendars, including a Birthdays calendar, that automatically retrieves dates of births from a user's Google contacts and displays the dates on a yearly basis, and a Holidays calendar, a country-specific calendar featuring dates of special occasions.

The user interface of Google Calendar was originally designed by Kevin Fox.[7] Google Calendar allows the user to import events from a different calendar application, with notable support for both Microsoft Outlook and Apple iCloud calendars.[8]


In December 2010, Google added the ability for users to select a time zone for an event,[9] a notable feature that was previously missing; the feature's absence was criticized in the media.[10]

In August 2015, Google added an "Events from Gmail" feature, where event information from a user's Gmail messages are automatically added to Google Calendar. The feature, enabled by default, will also update events with new information based on new email messages received, such as flight delays.[11][12]

In December 2015, Google added a "Reminders" feature, enabling users to add to-do activities as Reminders, with those activities being displayed in the calendar alongside regular events. Google also states that Reminders can automatically add additional, helpful information to Reminders based on known details, such as numbers or addresses. Reminders serves as a cross-service feature, meaning Reminders also show up in Inbox by Gmail, Google Now, and Google Keep.[13]

In January 2016, Google added "Smart Suggestions" to Google Calendar on the mobile apps. Smart suggestions recommend titles of events, as well as locations and contacts.[14] At the same time as Smart Suggestions, Google also added holiday calendars for 54 new countries, adding up to a total of 143 country-specific holiday calendars.[15]

In April 2016, Google added a "Goals" feature. Goals are activities the user wishes to complete. After answering brief questions, including "How often?" and "Best time?", Google Calendar will automatically "find the best windows to pencil in time for that goal", with the calendar adapting to the user's schedule over time, such as re-scheduling a goal activity if an event is added that causes a direct conflict with the time of the goal.[16][17] The feature was expanded in January 2017 with support for Google Fit and Apple Health, to see the progress made towards completing a goal.[18][19]

G Suite[edit]

Main article: G Suite

For users of Google's G Suite service, a subscription service for business, education and government customers offering additional functionality, Google Calendar has a "Find a time" feature that can suggest the best time for an event with a group of people, based on available times for each individual in the group. Additionally, the feature can also schedule the meeting room.[20][21]
