The Ancient Egyptian Civil (solar) Calendar is almost Identical to the one used by the Coptic Church today. It consists of three seasons of four months of 30 days each month, with the 13th month consisting of only 5 or 6 days. In addition, the ancient Egyptians used the Lunar Calendar for special festivals associated with the moon.
The Egyptian month is named after various ancient gods, and the same names are used by the Copts today. The following table shows the ancient Egyptian calendar, with similar spellings as used by the Copts shown in red. The modern equivalent is shown on the right. The New Year began on 11th of September, the month of Thoth.
