This is the calendar for any common year starting on Thursday, January 1 (dominical letter D). Examples include years 1970, 1981, 1987, 1998, 2009, 2015 and 2026 in the Gregorian calendar,[1] or 2010, 2021 and 2027 in the Julian calendar (see bottom tables).

In this common year, Martin Luther King Jr. Day is on January 19, Valentine’s Day is on a Saturday, Presidents Day is on February 16, St. Patrick’s Day is on a Tuesday, Mother’s Day is on May 10, Memorial Day is on its earliest possible date, May 25, Father’s Day is on its latest possible date, June 21, Independence Day is on a Saturday, Labor Day is on its latest possible date, September 7, Columbus Day is on October 12, Halloween is on a Saturday, Veterans Day is on a Wednesday, Thanksgiving is on November 26, and Christmas is on a Friday.

This is the only common year with three occurrences of Friday the 13th, in February, March and November. The other type of year with three occurrences of Friday the 13th is a Leap year starting on Sunday which has three Friday the 13ths in January, April, and July. Also interestingly, with the exception of skipped leap years, leap years starting on Sunday falls exactly three years either side of two consecutive common years starting on Thursday; the most recent occurrence was 2012 between 2009 and 2015.

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