Bank holidays and other closed-for-business days during which the whole company is not operating are called holidays in teamdeck.
You can manage holidays by going to the settings tab in the upper menu bar and picking holidays from the list.
Click on the plus sign in the bottom-right corner. Specify the date and name the holiday. When you’re ready to save, confirm it by clicking add new.
You can edit the holidays right from the list view. Simply click on the arrow next to the date to change it. If you want to change the holiday name, click on it.
You can remove holidays from the list view by clicking on the icon to the left of it.
