The Julian calendar was created by Julius Caesar, and is very similar to our modern (Gregorian) calendar, expect for the definition of the leap years, which was over-simplistic. A year was a leap year only if it was divisble by 4.
In Year 1582, Julian was 10 days ahead of schedule (according to vernal equinox in northern countries to be on March 21st) and those days had to be dropped. Between 1582 and 1970, Julian calendard has accumulated 3 more days ahead (on years 1700, 1800, 1900), so in Julian calendar, our origin of times is in fact: "19 Dec 1969 0:0:0" ("1st of Jan 1970" - 13 days)
