Any Jira user can create a number of calendars. By default, a new calendar is private, but the owner can share it with groups of users. There are two options:
sharing in view mode – users will be able to use calendar but will not have access to settings
sharing in edit mode – users will be able also to access settings and also to delete the calendar

Each calendar displays issues with defined timeframes (at least start). In the calendar settings, you can filter the issues to be displayed – by project, a saved filter, or a custom jql-query.
There are two zones in a calendar:
The issues that comply with the calendar scope but have their timeframes undefined are stored in the Unplanned Issues section. Use drag-and-drop to put those issues on the calendar.

Along with putting issues from the Unplanned section to the calendar grid, you can use other planning methods such as:
add a new issue directly from the calendar
put the existing issue on a particular calendar place via search
drag-and-drop an issue or stretch the issue timeframes within the calendar
drop the dates by removing an issue from the calendar
