I don't know how many of you use Mac OS X, but a calendar application has recently come out that may be of interest.
Kalendar is an application that figures the date of Pascha for any year from 1584 to 4098 and tells you the Gregorian date of it for any year. It can be downloaded by control-clicking on the link to it at http://www.scifihifi.com/kalendar/.
Its always nice to see an application written specificly for Orthodox Christians. Hope some of you find this useful and tell the application authors how much you appreciate Orthodox freeware! God Bless.
