Feast Calculator

Perpetual calendar for movable feasts and christmas
With the feast calculator you can determine the years, on which a certein holiday falls on a selected date.

In which years is Easter Sunday on April 25? Next time in 2038.
Later never, because the celebration happens between the dates March 22. and April 25.
The next "earliest" year is 2285. Then is also the earliest date for Shrove Tuesday: February 3.
The latest date for First Sunday Advent is naturally 12/3 as in the year 2006. Then Sunday Advent 4 and Christmas Eve will be at the same day.

Time Intervals

Daily distance
With the time interval computer the number of days between 1st and 2nd date as well as the next 1000-er anniversary from the first date will be computed.
Alternatively to it according to date a daily number before or after the first date can be determined.

Equal Years

To the selected year all weekday-same years are indicated. Practically to the re-use of old calendars.
For the year 2007 the calendars of 2001, 1990, 1979, 1973 e.g. leave themselves or - who has still - from 1590.
In the year 2008 the selection is then smaller, because 2008 is a leap year.
Note: The movable feasts such as Easter, Pentecost etc. do not mach in general.

Note: Boys usually come earlyer to the world than girls. Girls still "groom" themselves.
A deviation of the birth date from plus/minus 10 days is quite considered as normal.
