Advanced: Calendar

Advanced adds a full Calendar tab — plan when to work your Jira issues, then log actuals when you work. Standard still supports scheduled events inside My Week, but not this full view.

Plan when to work a Jira issue — Plan when to work an issue

Open Calendar from the left rail.
Place or adjust planned work for issues on the calendar.
When you work the issue, log time as usual from My Week or Time Log (timers or + Time).
