Calendar settings & booking rules

Operating hours and slot length

1. Open Settings → Calendar settings.
2. Set the time the calendar opens and closes each day.
3. Choose the booking interval — 15, 30, 45, or 60 minutes. This is the smallest unit members can book.
4. Save.

User booking rules

1. Open Settings → User booking rules.
2. Set how far in advance members can book (e.g. 90 days).
3. Set the minimum notice required to make a booking (e.g. members can't book a slot starting in less than 15 minutes).
4. Set whether members can book retrospectively for the past. Most workspaces leave this off — owners can override on a case-by-case basis from the calendar.

Theme and visible columns

From the same Calendar settings page you can also set the calendar theme and choose which days appear in the week view by default. These are presentation choices — they don't change what's bookable.
