The Julian calendar is primarily used by some religious communities and in a few countries for specific purposes. Currently, the most notable users of the Julian calendar are:
- Russia: The Russian Orthodox Church continues to use the Julian calendar for its liturgical purposes, which results in a difference of 13 days from the Gregorian calendar.
- Serbia: Similar to Russia, the Serbian Orthodox Church utilizes the Julian calendar for its religious observances.
- Other Orthodox Churches: Certain other Orthodox Christian communities, including those in Ethiopia and parts of the Middle East, also adhere to the Julian calendar for their religious events.
It’s important to note that while these religious groups use the Julian calendar for their traditions, most countries have transitioned to the Gregorian calendar for civil purposes.
