Common year starting on Thursday

A common year starting on Thursday is any non-leap year (i.e. a year with 365 days) that begins on Thursday, 1 January, and ends on Thursday, 31 December. Its dominical letter hence is D. The current year, 2026, is a common year starting on Thursday in the Gregorian calendar, and the next such year will be 2037, or, likewise, 2021 and 2027 in the obsolete Julian calendar, see below for more.

This is the only common year with three occurrences of Friday the 13th: those three in this common year occur in February, March, and November. Leap years starting on Sunday share this characteristic, for the months January, April and July. From February until March in this type of year is also the shortest period (one month) that runs between two instances of Friday the 13th. Additionally, this is the one of only two types of years overall where a rectangular February is possible, in places where Sunday is considered to be the first day of the week. Common years starting on Friday share this characteristic, when Monday is considered to be the first day of the week.

Any common year that starts on Thursday has only one Saturday the 13th: the only one in this common year occurs in June. Leap years starting on Wednesday share this characteristic.

This year has four months (February, March, August, and November) which begin on a weekend-day. Leap years starting on Wednesday share this characteristic.
