A **leap year starting on Tuesday** is any year with 366 days (i.e. it includes 29 February) that begins on Tuesday, 1 January, and ends on Wednesday, 31 December. Its dominical letter hence is **FE**, such as the years 1952, 1980, 2008, 2036, 2064, 2092, and 2104 in the Gregorian calendar or, likewise, 1992 and 2020 in the obsolete Julian calendar.

## Gregorian Calendar

Leap years that begin on Tuesday occur at a rate of approximately 14.4% (14 out of 97) of all total leap years in a 400 year cycle. Their overall occurrence is thus 3.5% (14 out of 400).

## Julian Calendar

Like all leap year types, the one starting with 1 January on a Tuesday occurs exactly once in a 28-year cycle in the Julian calendar, i.e. in 3.57% of years.

The final two digits of Julian years repeat after 700 years, i.e. 25 cycles.
