Setting up schedules and Happy Hour

Each promotion's schedule has three layers: a date range (start required, end optional), a daily time window (Happy Hour), and selected weekdays. All three must match for the promotion to fire.

• For cross-midnight windows (e.g. 22:00–02:00), the weekday is judged by the day the window starts: with only Friday selected, Saturday 01:30 still counts as Friday's session and fires — but Saturday 23:30 does not.
• The end date is a hard cutoff — even if a Happy Hour window is still running, the promotion stops the moment the end date passes.
• Time is read from the iPad's device clock, so make sure the device time zone and time are correct.
