You can mark any day as closed in the Boarding Calendar form by following these steps. Note that you can still add boarding bookings to a day marked as closed, you will just be prompted about this when making the booking.
- Open the Boarding Calendar form if it is not already open.
- Click on the required day in the month view to bring that date range into view, and then click on the required date in the grid.
- Click on the Boarding Closed button in the Calendar ribbon OR right-click and choose Mark Day as Closed from the menu. Choosing this option again will set the day back to a normal working day again.
