Cancel every class on a specific day with one click — credits and pass uses are auto-refunded. Nothing new can be scheduled or booked on a closed day.
Click + Add closure.
Set the date and give it a label (e.g. "Independence Day", "Owner vacation"). Save.
Every non-cancelled class session on that date is automatically cancelled and the affected bookings have their credits or pass uses refunded in one step. The reason on each cancelled session is auto-set to "Studio closed: [your label]".
From then on nothing new lands on that date: recurring classes skip it when Klasly extends the schedule, Add Session, repeating series, the schedule import and room bookings leave it out (and tell you which dates were skipped), and no appointment time is offered or accepted — online, in the member app, or when staff book for a client.
