Common year starting on Thursday

This is the calendar for any common year starting on Thursday, January 1 (dominical letter D). Examples: Gregorian years 1981, 1987, 1998, 2009, 2015, 2026, 2037, and 2043 or Julian year 1915 (see bottom tables).

This is the only common year where three Friday the 13ths can happen; specifically, the months of February, March, and November. Leap years starting on Sundays share this characteristic.

A common year is a year with 365 days, i.e. not a leap year.
