Stan is right.  I double-checked "Normally" there is no leap year at the
end of a Century "except" those divisible by 400.  From CalTech:

Summary:   In the Gregorian Calendar currently in use worldwide, there is
a leap year every year divisible by four except for years divisible by
100 and not divisible by 400. Therefore, the year 2000 will be a leap
year.

Only in the sense that 2000 is evenly divisible by 400. :)

2000 is a leap year, so 2000-02-29 is a valid date that year.
