Health care institutions:
On non-working holidays only after-hours shops and institutions are open. If the second day of a two-day holiday falls on a Sunday, then Monday is also a non-working day.
All Serbian citizens are entitled to non-working holidays for their own religious festivals, depending on their faith.
The Serbian Orthodox Church calculates its religious festivals according to the old, Julian calendar, which runs behind the Gregorian calendar by 14 days.
