Editing Leap year starting on Tuesday

{{Short description|none}}
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]]s hence are '''FE'''. The most recent year of such kind was [[2008]], and the next one will be [[2036]] 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 [[2020]] and [[AD 2048|2048]] in the obsolete [[Julian calendar]].

Any leap year that starts on [[Tuesday]] has only one [[Friday the 13th]]; the only one in this leap year [[June 13|occurs in June]]. [[Common year starting on Wednesday|Common years starting on Wednesday]] (such as 2025) share this characteristic.

Any leap year that starts on Tuesday has only one [[Tuesday the 13th]]: the only one in this leap year [[May 13|occurs in May]].

Any leap year that starts on Tuesday has only one [[Friday_the_13th#Friday_the_17th_in_Italy|Friday the 17th]]: the only one in this leap year [[October 17|occurs in October]].

From [[August]] of the [[Common year starting on Monday|common year preceding that year]] until [[October]] in this type of year is also the longest period (14 months) that occurs without a [[Friday the 13th #Friday the 17th in Italy|Friday the 17th]].

=== Julian Calendar ===
Like all leap year types, the one starting with 1 January on a Tuesday occurs exactly once in a [[solar cycle|28-year cycle]] in the Julian calendar, i.e. in 3.57% of years. As the Julian calendar repeats after 28 years that means it will also repeat after 700 years, i.e. 25 cycles. The year's position in the cycle is given by the formula ((year + 8) mod 28) + 1).
