Yes, because it's always on the same date (like all the other Festive Days) in the Jewish calendar. 14-21/22 Nisan. http://nl.wikipedia.org/wiki/Pesach -- Ruud Harmsen, http://rudhar.com |

When accompanied by clear weather, as it often is, the full Easter moon on the snow gives enough light to perform most tasks unaided. A great help for those who spend Easter carrying a tent around in the mountains. Clearly, a calendar that doesn't accomodate the needs of such an important group isn't worth the van Gogh reproductions. -- Trond Engen |

If it is, then I question the need for every country in the world to celebrate purely USA political and social events (the yellow shaded days), which were said to be "permanently fixed". On that basis alone, I would say it resoundingly fails. How can you even *think* that is the case?? How can you even *notice* the holidays shown are US-specific? Obviously the US holidays are there to illustrate how it works, not to be used universally. Likewise the numerals and month names. Sheesh. |

The Muslim calendar -- no intercalated months, and no connection with the solar year. So Ramadan drifts through the seasons. Ramadan is celebrated according to the actual siting of the crescent, not the (various) algorithms used for civil purposes, though I think some "cheat" by using the algorithms (there are a couple most frequently used). last time in Iraq the Shia and the Sunni observed it at different dates. so it is rather complicated. |

Also, in a Bissextile Year "the number of Sundays after Epiphany will be the same, as if Easter Day had fallen one day later than it really does." the Orthodox (Eastern) churches have a slightly different system. dunno exactly what it is. http://en.wikipedia.org/wiki/Easter Easter .... Easter is a moveable feast, meaning it is not fixed in relation to the civil calendar. The First Council of Nicaea (325) established the date of Easter as the first Sunday after the full moon (the Paschal Full Moon) following the vernal equinox.[3] Ecclesiastically, the equinox is reckoned to be on March 21 (regardless of the astronomically correct date), and the "Full Moon" is not necessarily the astronomically correct date. The date of Easter therefore varies between March 22 and April 25. Eastern Christianity bases its calculations on the Julian Calendar whose March 21 corresponds, during the twenty-first century, to April 3 in the Gregorian Calendar, in which calendar their celebration of Easter therefore varies between April 4 and May 8.
