Common year starting on Saturday

A common year starting on Saturday is a common year that begins on Saturday, January 1, and ends on Saturday, December 31. Thus, its dominical letter is B.  Examples include 1977, 1983, 1994, 2005, 2011, 2022, and 2033 in the Gregorian calendar, or likewise, 1995, 2006, 2017, 2023 and 2034 in the Julian Calendar (see tables below for more).

In this common year, January and October begin on Saturday, February, March, and November begin on Tuesday, April and July begin on Friday, May begins on Sunday, June begins on Wednesday, August begins on Monday, and September and December begin on Thursday. Thus, there are three months that begin on a weekend day. This is one of two common years with this property, the other being Common year starting on Tuesday.

This common year is one of three common years with only one Friday the 13th, the others being Common year starting on Wednesday and Common year starting on Friday. The Friday the 13th in this common year is in May. This characteristic is shared with a Leap year starting on Friday.

This common year is one of three common years with only one Friday the 17th, the others being Common year starting on Monday and Common year starting on Tuesday. The only Friday the 17th in this common year is in June. Leap years starting on Friday share this characteristic.

This common year is one of three common years with two Tuesday the 13ths, the others being Common year starting on Thursday and Common year starting on Friday. The Tuesday the 13ths in this common year are in September and December. Leap years starting on Friday share this characteristic. From July of the year preceding this type of year (either a Leap year starting on Thursday or Common year starting on Friday) is the longest period (14 months) between two instances of Tuesday the 13th. Leap years starting on Wednesday share this characteristic, from August of the year that precedes it (Common year starting on Tuesday) to October in that type of year.

In this common year, Martin Luther King Jr. Day is on January 17, Valentine’s Day is on a Monday, Presidents Day is on its latest possible date, February 21, Daylight Savings Time begins on March 13, St. Patrick’s Day is on a Thursday, Mother’s Day is on its earliest possible date, May 8, Memorial Day is on May 30, Father’s Day is on June 19, Independence Day is on a Monday, Labor Day is on September 5, Columbus Day is on October 10, Halloween is on a Monday, Daylight Savings Time ends on November 6, Veterans Day is on a Friday, Thanksgiving is on November 24, and Christmas is on a Sunday. 

In a 400-year cycle in the Gregorian Calendar, 43 or 10.75% of all years are common years starting on Saturday. Like all common years, they occur in a pattern of 6-11-11 years (e.g. 2005, 2011, 2022, 2033). However, this pattern gets broken when there is a century year that is not a leap year. Over the past 400-year cycle (from 1600 to 2000), there were 6-year gaps between 1689, 1695, 1701 and 1707, a 12-year gap between 1791 and 1803 and another 12-year gap between 1898 and 1910. In the Julian Calendar there are three common years starting on Saturday in a 28-year cycle.
