Editing Leap year starting on Thursday (section)

{{Short description|none}}
A '''leap year starting on Thursday''' is any year with 366 days (i.e. it includes 29 February) that begins on [[Thursday]] 1 January, and ends on [[Friday]] 31 December. Its [[dominical letter]]s hence are '''DC'''. The most recent year of such kind was [[2004]], and the next one will be [[2032]] in the [[Gregorian calendar]]<ref name="math">{{cite web|url=https://webspace.science.uu.nl/~gent0113/calendar/isocalendar.htm |author=Robert van Gent |title=The Mathematics of the ISO 8601 Calendar |publisher=Utrecht University, Department of Mathematics |date=2017 |access-date=20 July 2017}}</ref> or, likewise, [[2016]] and [[2044]] in the obsolete [[Julian calendar]].

This is the only leap year with three occurrences of [[Friday the 13th#Tuesday the 13th in Hispanic and Greek culture|Tuesday the 13th]]: those three in this leap year occur three months (13 weeks) apart: [[January 13|in January]], [[April 13|April]], and [[July 13|July]]. [[Common year starting on Monday|Common years starting on Monday]] share this characteristic, in the months of February, March, and November.

Any leap year that starts on [[Thursday]] has two [[Friday the 13th]]s: those two in this leap year [[February 13|occur in February]] and [[August 13|August]]. This is also the only year in which February has five Sundays, as the leap day adds that extra Sunday.

This year has three months (February, May and August) which begin on a weekend-day.
