It is possible in Vetocare to incorporate the national holidays into the calendar. The holidays are included as normal appointments in the calendar. If you have multiple calendars, they will be included in the general calendar. To add the holidays to the calendar, go to the "Settings". Here you choose the "Holidays" option under the heading "Calendar". Here you have the option to add the holidays of some countries. Press the"Add"button next to the country you want to add the holidays from. It can take a few seconds after pressing, after which the button changes to a "Delete" button. The delete button removes all holidays from that country again.
