For example, if you need to work out how many years are between January 1, 200 B.C. In other words, October in the year 1664 was 1,663.75 years after January 1, A.D. Here is the earlier example again written in both conventions: The simplest method is to take the starting calendar year and figure out how much time has lapsed since January 1, A.D.
