I'm asking because it makes some things really nice for some math I'm doing.
I'll post it when I find it if no one gets to it first

Argh, I read over the "leap year" part of the sentence. So it's not the year 3, but 20. Of course, this is using the Julian calendar, currently we use the Gregorian calendar. The Julian calendar had leap days (on February 24), but not the exception every 100 years. See Proleptic Gregorian calendar for more information, including the differences over time.

Julian and Gregorian should be the same in year 20, Gregorian only changed the century rules.

As it happens the Gregorian calendar has year 1 as starting on a Monday (.NET's DateTime starts on a Monday :)

A:
According to Mathematica's "DayOfWeek" function, 20 AD is the first such leap year.
DayOfWeek[{20,1,1}] == Monday
But there are a lot of caveats about what to consider to be the day of the week before Europe switched from the Julian to Gregorian calendar.
