FAQ
What is the Julian calendar?
The Julian calendar is a historical dating system introduced by Julius Caesar in 45 BCE.
When was it replaced by the Gregorian calendar?
The Gregorian reform started in 1582. At that time, the correction was 10 days, and the difference changed over the centuries.
Why is there a date difference between Julian and Gregorian?
The calendars use different leap-year rules. Because of that, the offset gradually increased over time.
Why is the Julian calendar still useful today?
It is useful for historical sources, archives, chronology research, and some religious references.
