It's easy! See Install Team Calendars.

Team Calendars is compatible with Confluence 3.5.x and later versions, but there may be some features that require a specific version of Confluence. Check the Team Calendars Compatibility Chart for more info.

There are a few reasons:

• We feel we can solve a lot of specific problems with the combination of events, people, projects (JIRA applications) and content. Atlassian sees this plugin working alongside your personal meeting or events calendar.
• Not every customer needs a team calendaring solution. Hence, by not bundling Team Calendars with Confluence, it doesn't increase the cost of Confluence for those customers who aren't going to use it.
• The old plugin was not maintained or supported. In contrast, Team Calendars is maintained and supported moving forward.

The old calendar plugin was never officially supported and as such carries no support from Atlassian. The old calendar plugin does not work with Confluence 3.5.x or later versions. There are currently no plans to continue development on the old calendar plugin. If you are currently using the old plugin, there is a manual migration path to Team Calendars available by importing your iCal files.

Yes you can! See Add Jira Events to find out more.

Maybe! It depends whether you have a calendar app that supports iCal or CalDAV. See Subscribe to Team Calendars from Third-Party Calendars to find out how to get set up.

Yes you can. Just add multiple names in the people field.

Team Calendars is available in English and many of the the bundled Confluence languages. See Choosing a Default Language for a list of languages available in Confluence.

The date format is dependent on your language settings and automatically adjusts accordingly - this is a Confluence user and global setting. An admin can set the site default language (see Choosing a Default Language) and you can also set your preference (see Edit Your User Settings).

Team Calendars uses the language set in each user's profile to determine which day of the week should be the first day in the calendar. For example, if a user has selected US English, Sunday will be the first day of the week. If they select UK English, Monday will be the first day of the week.

If you want to override the default for all users, regardless of their profile setting, go to > General Configuration > Team Calendars and choose a specific day of the week.

Currently, it's not possible to subscribe to Google Calendar from Team Calendars using Public URL to this Calendar from Google. This is a known issue with Google Calendar; it appears that Google Calendar Public URL doesn't contain the data/event that can be read by Team Calendars to display events. You can subscribe to Google Calendar from Team Calendars using these links:

• Secret address in iCal format
• Public address in iCal format (if your calendar is made available to the public)

Events from JIRA and external calendars are cached to help your calendars load more quickly. The cache expiry (time to live) defaults to 10 minutes, and is configurable. Go to Team Calendars > General Settings and decrease the Cache expiry time if you want these events to update more frequently.
