Calendar
See scheduled work on a calendar — across a project or across everything assigned to you.
The calendar places dated tasks on a familiar month or week grid, so you can see timing at a glance. It is especially useful for finding collisions, empty periods, and work that has a date but no realistic place in the surrounding schedule.
Project vs. personal calendar
A project's calendar shows that project's dated tasks, while your personal calendar brings together everything scheduled across all your projects in one view.
Tasks use their start and end dates when they are scheduled across a range. Mark an item all-day when it should not imply a specific time of day.
Rescheduling
Drag a task to a new day to change its date right from the calendar — no need to open it. Open the task when you need to change more than its timing, such as the owner, description, labels, or the project section it belongs to.
Calendar is a view of existing tasks, not a separate planning record. Changing a date there updates the task everywhere it appears.
