Leap year starting on Friday

A leap year starting on Friday is any year with 366 days (i.e. it includes 29 February) that begins on Friday 1 January and ends on Saturday 31 December. Its dominical letters hence are CB. The most recent year of such kind was 2016, and the next one will be 2044 in the Gregorian calendar or, likewise, 2000 and 2028 in the obsolete Julian calendar.

Any leap year that starts on Friday has only one Friday the 13th: the only one in this leap year occurs in May. Common years starting on Saturday share this characteristic. This is also the only year in which February has five Mondays, as the leap day adds that extra Monday.

This year has two months (May and October) which begin on a weekend-day. Since at least one month begins on each day of the week in all years, this is the fewest possible number of months to begin on a weekend-day in a given year; this also occurs in a common year starting on Friday, in which case the two months are May and August.
