Julian Calendar Proclaimed In Rome
About this moment
The Julian calendar is a solar calendar of 365 days in every year with an additional leap day every fourth year (without exception). The Julian calendar is still used as a religious calendar in parts of the Eastern Orthodox Church and in parts of Oriental Orthodoxy as well as in the Berber calendar. For a quick calculation, between 1901 and 2099 the much more common Gregorian date equals the Julian date plus 13 days (for instance Julian 1 January falls on Gregorian 14 January).
