Summary

This article will provide steps on how to change the time format from AM/PM to 24H ( also known as "Military time" format ) while specifying the start and end time for Events in Team Calendar.

Solution

When you open a Team Calendar and click on a date in order to bring up a Create Event window, if you un-tick the All day event check box, two boxes will show up to enter the start and end time.

By default, time will be presented in AM/PM format. To change the time format from AM/PM to 24H format, go to !https://confluence.atlassian.com/conf75/files/1004946117/1004946118/1/1590042964839/cog.png|width=16! > General Configuration > Team Calendars and change the 'Display time format' setting from 1:00 PM to 13:00 (24-hour time) or vice versa.
