Your bookable hours are set by your price list: any priced court time is bookable; unpriced time is not. 🗓️
To change bookable hours long-term:
Settings → Price Lists → Standard Price Lists → open your list
Click the ⋮ next to a price variant → Edit
Adjust the Opening days and times for that variant → Save
To close just a day or two (e.g. a holiday or event), don't change the price list — instead create an Unavailable booking in the schedule: highlight the times/courts → Unavailable → save.
ℹ️ The opening hours shown on your public club info page (Settings → The club → Opening Hours) are display-only and separate from what's actually bookable.
