Did you ever need to look-up when Easter Sunday or Passover will be this year? Even though many of the religious holydays occur on the same date of the Hebrew calendar every year you may not know the corresponding date on the Gregorian calendar. HolyDates provides a quick answer to these questions.

HolyDates uses algorithms provided by Jean Meeus in his book, “Astronomical Algorithms” second edition. His methods have become a sort-of standard for these sorts of computations.

The information and functionality provided by HolyDates is divided onto several screens:
