Years with Same Calendar as 1931 – Extended Range

The year 1931 had 365 days and started on a Thursday (Tanzania, Gregorian calendar).

This country introduced the modern Gregorian calendar in year 1582, so previous years are based on the Julian calendar. In that calendar system, a Leap Day was added every four years, without the exceptions defined in today's Gregorian calendar. This affects the selection of years listed here.
