How do I edit a public holiday?

To edit a public holiday, select “Administration” from the main menu, then select the “Public Holidays” option. You are then shown a list of Public Holiday Schedules. Click on the "Holidays" button for the schedule that contains the holiday you wish to edit and then, on the page that is displayed, you may edit a holiday by clicking on the “Edit” button alongside the holiday you wish to edit.
