Active vs Closed days

Each day can have one or more time blocks (example: Morning and Afternoon).

• Edit (pencil): change the time range

• Delete (trash): remove a block

• + Add: add another block (split shifts, lunch breaks, etc.)

• Good to know

  • Set Weekly Availability first, then use Blocked Dates for exceptions (holidays, vacations, closures).

  • If bookings aren’t working as expected, confirm:

    • The correct calendar is selected and visible in My Calendars

    • The day is Active

    • Availability blocks exist for that day

    • The date is not listed under Blocked Dates

    • You aren’t filtering the view with Show only this calendar

   3. Create a second calendar (example: Marketing) from the Business Calendars Dashboard.

   4. Use the ⋯ menu → Show only this calendar to confirm filtering works.
