Explanation of the annual cycle

The fixed part of the graphic displays the immovable, while the animated part illustrates the movable festivals and festival dates in the course of the Christian year. As Easter Sunday is, since the council of Nicaea (325 anno Domini.), fixed to the Sunday after the first full moon in spring, the greatest possible date fluctuation of Easter is scheduled 35 days (= duration of a moon rotating phase of 28 days plus maximally 7 working-days up to the latest possible determination of Easter Sunday). Therefore, Easter cannot take place before the 22.03. and after the 25.04. The movable festivals as Carnival, Ascension Day, Pentecost and Corpus Christi are also geared to the movable Easter dates.

Maximum date fluctuations of festivals dependent on Easter:
Carnival Tuesday   (=47th day before Easter)  03. 02. - 09. 03.
Easter Sunday:  -  22. 03. - 25. 04.
Ascension Day/
Early May Bank Holiday
 (=40th day after Easter)  01. 05. - 04. 06.
Pentecost  (=50th day after Easter)  11. 05. - 14. 06.
Corpus Christi  (=60th day after Easter)  21. 05. - 24. 06.

These dates relate to the normal year. Regarding the leap year, dates which are prior to the 29th of February have to be calculated backwards from Easter and therefore the formula n+1 has to be applied. Consequentially, the earliest Carnival date in the course of the leap year has to be the 04.02. while the latest Carnival date remains at the 09.03. as the date is subsequent to the 29.02. Ascension Day, Pentecost and Corpus Christi remain also unchanged as these dates are situated after the 29th of February.

The postponement of the Easter schedule occurs relatively rarely. The earliest possible date (Easter at 22.03.) appeared and appears in the period from 1600 until 2500, a range of 900 years, only six times. Namely in the year of 1669 (leap year) , 1761, 1818, 2285, 2353 and 2437. The latest possible date (Easter at 25.04.) appeared and appears in the same period only 9 times, namely in the year of 1641, 1736 (leap year), 1886, 1943, 2038, 2190, 2258, 2326 and 2410.
