St. Vitus' Day (Vidovdan)

Although not a public holiday, St. Vitus’ Day (Vidovdan) is one of Serbia’s most important religious and historical observances. It’s held every year on June 28 to commemorate the Battle of Kosovo in 1389, where Serbian forces fought the Ottoman Empire.

What’s it for you as a traveler: You won’t encounter road closures or transit reroutes, but you may notice larger crowds at Orthodox centers where memorial services are held.
