Ponomar Project  Ponomar -> Paschalion : Online perpetual Paschalion 

Perpetual Paschalion calculator

This script will calculate Pascha and associated feasts (Palm Sunday, Ascension, etc) for any period of years. You can enter any sequence years, at most 99 years apart.
Alternatively, it can also calculate a perpetual table of numbers used to calculate a Paschalion, such as one would find in the back of a Typicon. Thanks to Gregory Douglas for information leading to the creation of this feature.

Start: Stop: (Dates must be after 313 AD, and at most 99 years apart)

Calculate a Paschal Table
Calculate a Typicon-style Paschalion
Calculate Orthodox Pascha, Gregorian Easter, and Jewish Passover

Known Issues: For the display of the tables, the utility uses Church Slavonic fonts, which can be downloaded here. The fonts are a Unicode (UTF-8) implementation of Church Slavonic. They have been tested and work well on Fedora 4.
Thanks also to Deacon David Keim for pointing out a bug in the Julian-Gregorian conversion algorithm. That has been fixed.
