1926

1926 (MCMXXVI) was a common year starting on Friday of the Gregorian calendar, the 1926th year of the Common Era (CE) and Anno Domini (AD) designations, the 926th year of the 2nd millennium, the 26th year of the 20th century, and the 7th year of the 1920s decade.

In Turkey, the year technically contained only 352 days.

As Friday, December 18, 1926 (Julian Calendar) was followed by Saturday, January 1, 1927 (Gregorian Calendar).

13 days were dropped to make the switch.

Turkey thus became the last country to officially adopt the Gregorian Calendar, which ended the 344-year calendrical switch around the world that took place in October, 1582 by virtue of the Papal Bull made by Pope Gregory XIII.
