What is Leap year starting on Sunday?
A '''leap''' '''year starting on Sunday''' is any leap year (i.e. a year with 366 days) that begins on Sunday, 1 January, and ends on Monday, 31 December. Its dominical letter hence is '''AG'''. Examples include [[1928]], [[1956]], [[1984]], [[2012]], [[2040]], [[2068]], and [[2096]]. In this leap year January, April, and July begin on Sunday, February and August begin on Wednesday, March and November begin on Thursday, May begins on Tuesday, June begins on Friday, September and December begin on Saturday and October begins on Monday. This is the only leap year with three occurrences of [[Friday the 13th]]. The Friday the 13ths in this leap year are [[January 13|in January]], [[April 13|April]] and [[July 13|July]]. The other type of year with three occurrences of Friday the 13th is a [[Common year starting on Thursday]], which has Friday the 13ths [[February 13|in February]], [[March 13|March]], and [[November 13|November]]. From July of this type of year to [[September 13|September]] of the following year ([[Common year starting on Tuesday]]) is the longest period (14 months) between two instances of Friday the 13th. Interestingly, 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.
