Some believe that St. Catherine (along with St. [[Mercurius the Great-martyr]]) was celebrated originally on [[November 24]], whereas the holy [[Hieromartyr]]s [[Clement of Rome]] and [[Peter of Alexandria]] were celebrated on the [[November 25|25th]]. The belief that St. Catherine's feast day was changed to November 25 at the request of the [[St. Catherine's Monastery (Sinai)|Church and Monastery of Sinai]], so that the festival of Catherine, their [[patron saint|patron]], might be celebrated more festively together with the [[leavetaking]] of the [[Presentation of the Theotokos]], is contradicted by original documents at the Sinai Monastery. The Imperial Holy and God-trodden Monastery of Sinai which popularly bears the name of St. Catherine, along with the world wide Greek Orthodox Church continues to commemorate the Great Martyr and Bride of Christ on November 25. The Slavic churches, however, continue to commemorate these saints on the dates as mentioned above.{{ref|1}}
