>>1st century B.C. March 1st.

>>By the way, 2000 is leap year, 1600 is leap year. 0400 is leap year. and so B.C. is also a leap year. May be because of that Sys(11) function is giving upto March 1st 1st B.C.

>>Is really 1st B.C. is leap year?

>The reason the calendar was changed in 1752 was because the old calendar had drifted ahead because the old leap year occurred every 4 years even if it was a century year. The reformed calendar specified that a century year was only a leap year if divisible by 400 to keep the calendar in sync. This means that 1700, 1600, 1500, 1400, ... are all leap years

Ummm...that means evenly divisible...only 1600, 2000, etc. are leaps.
