Years with Same Calendar as 1731 – Extended Range

The year 1731 had 365 days and started on a Friday (Papua New Guinea, Julian calendar).

This country was still using the Julian calendar in year 1731. In that calendar system, a Leap Day was added every four years, without the exceptions defined in today's Gregorian calendar. The Gregorian calendar was introduced in 1752. This affects the selection of years listed here.
