Mark a date range with a period

Add a trip or project bar without moving its events.

Mark a date range with a period

A period names a stretch of time, such as a trip or project, and appears as a bar across those dates. Events that fall inside the range keep their own calendar, type, and color. Periods can overlap.

Create a period

Press ⌥P from the calendar, or choose Add new (+), then Add period. This works the same on a phone.

Enter a name, choose the dates and appearance, and choose the period's calendar. You can also add labels, notes, and a checklist. Choose Add period (⌘↵, or Enter in the name) to add it. Closing the editor after you've changed anything adds it too, with Undo to take it back; closing it untouched discards it. Once it's added, changes save automatically.

Where periods appear

In Week view, period bars stack in the all-day lane. In Month view, they span the days they cover. A bar runs off the edge when the period extends past the visible dates.

Press ⌥⇧1 through ⌥⇧9 to jump to a period by its number.

Edit or archive a period

Click a period bar to open it. Periods on read-only calendars cannot be changed.

Archive a period from its editor to remove the bar. The events inside its dates are not affected. Restore the period from Settings → Archive within 60 days.
