Greek Calendar is totally wrong

Greece does not have an ASH WEDNESDAY. That is a Catholic thing. We do not have EASTER. We have Pascha. I would not use something that refered to the Catholic name. St John's Day is missing as is the beginning of Lent or Advent. The Celebration of the Theotokos is missing, 8/15. The beginning of the Church Calendar 9/8/11 is missing as are other major Religious holidays. To me these are serious oversights and would stop me from buying it.
