no data generated for the 2nd of March for non-leap years

[gregrahn]

There appears to be a bug in the data generation that only generates data for the 2nd of March when the year is a leap year, in this case year 2000. As a result, 1998, 1999, 2001, and 2002 have no data for the 2nd of March. This means 1823 of 1827 days have data for the given date range, 1998-01-02 to 2003-01-02.

Not a critical bug, but documenting it.
