Calendar Difference: Gregorian versus Julian of Eastern Europe
The Julian calendar was a reformed calendar from the Roman Calendar created by Julius Caesar. It was used in 45 BCE onwards till 1582 when Pope Gregory introduced his Gregorian Calendar, which is still in use today. The Julian calender went from vernal equinoxes to the next vernal equinox and consisted of 365.25 days, well, actually 11 minutes shorter than that.
The Gregorian calendar is 12 days later (also 13 sometimes) than the Julian calendar used by our ancestors in eastern Europe. That accounts for the differences: our forefathers were not aware of this. (Dennis Kahn)The Gregorian calendar has 365 days, 5 hours, 49 minutes and 12 seconds. Leap year every 4 years adjusts the time.
Russia changed over to the Gregorian in 1918.
Prussia changed in 1700.
The British Empire changed in 1752.
Most all countries had changed over by 1927.
Now when we get dates in our genealogy research I'll wonder which calendar was used and will have to look at the dates involved. The question of different calendars is clearly shown by Christine Usdine. She researches Latvian sources for jewishgen. In each of her birth, marriage and death presentations she tells one how many days to add to get our date. Her email: uzdine@orange.fr from Dennis Kahn.
