Years with Same Calendar as 2121 – Extended Range

The year 2121 has 365 days and starts on a середа (Ukraine, Gregorian calendar).

This country introduced the modern Gregorian calendar in year 1918, 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.
