Find Sunday on Calendar

[it15]

Hi, I have a booking app with a clickable calendar for users.
Any idea how I can identify Sundays for my calendar (because I want to block Sundays for booking)?

p.s. I’m able to identify dates in the past (grey cells in screenshot), but don’t know how to identify dates based on which day of the week they are.

Hi there, @it15… if you use the :extract operator on a date and select day as the component to extract from the date, you can see if the day is a Sunday by seeing if the day component is 0.

Hope this helps.

Best…
Mike
