Шаблон:Use dmy dates

A concurrent was the weekday of 24 March in the Julian calendar counted from Шаблон:Nowrap, regarding Шаблон:Not a typo as Sunday. It was used to calculate the Julian Easter during the Middle Ages. It was derived from the weekday of the first day of the Alexandrian calendar during the 4th century, Шаблон:Nowrap Шаблон:Nowrap, counting Wednesday as Шаблон:Not a typo (see Planetary hours#History). Therefore, the following Шаблон:Nowrap was a Sunday and the following Шаблон:Nowrap Шаблон:Nowrap [[[:Шаблон:Nowrap]] Шаблон:Nowrap] was also a Sunday.[1][2] It was first mentioned by Dionysius Exiguus in 525 in his Latin version of the original Alexandrian Church's Greek computus.[3] The insertion of the sixth epagomenal day Шаблон:Nowrap immediately before Шаблон:Nowrap was compensated for by the bissextile day Шаблон:Nowrap inserted six months later into the Julian calendar.

The widely used post-Bedan solar cycle (first year 776), which repeats every 28Шаблон:Nbsyears, had concurrents of

1 2 3 4 6 7 1
2 4 5 6 7 2 3
4 5 7 1 2 3 5
6 7 1 3 4 5 6.

It skips a concurrent every four years due to a bissextile day in the Julian calendar a month earlier.[4][5] The Sunday after the next Шаблон:Nowrap was Easter Sunday (see Computus#Julian calendar). The concurrent is not used by the Gregorian Easter.
