Availability sessions
Availability sessions are bookable slots that Pay2Book generates from your rules, rather than events you place by hand. You set this up per service when you choose Set availability.
There are three parts: your weekly hours decide when you are open, date overrides adjust specific dates, and your calendars subtract time that is already taken.
Weekly hours
Section titled “Weekly hours”Your weekly hours are the foundation - they decide when you are bookable.

Turn a day on and add one or more time ranges. Two ranges with a gap give you a lunch break. A day left off is closed. Pay2Book offers slots within these hours, spaced to fit the service’s length.
Date overrides
Section titled “Date overrides”Date overrides let you change specific dates without touching your weekly schedule.

Use them to block a holiday or a week away, or to set special hours for a particular date. Pick a date range, or the same date twice for a single day. Overrides win over your weekly hours for those dates.
Calendars: subtracting booked and busy time
Section titled “Calendars: subtracting booked and busy time”This is what keeps Pay2Book from double-booking you. For each calendar connected to the service, you choose what it does.

Your weekly hours decide when you are bookable; these calendars then subtract time that is already taken. For each calendar you can set:
- Block busy events - events marked busy on that calendar remove their time from your availability. This is the usual setting for your main calendar, so a meeting already in your diary blocks that slot.
- Block all events - every event blocks, busy or not. Useful for a calendar where any entry should hold your time.
- Don’t block - the calendar does not affect availability (you might use this for a calendar you only read for another reason).
One calendar is your booking target - the calendar confirmed bookings are written to. You can change which calendar that is.
Note: The Free events are bookable checkbox on each calendar is a different feature - it turns specific events into bookable Calendar sessions, rather than blocking time. You can use it alongside your availability rules, or on its own.
