calendar Date conversion between different calendar formats hholzgra Hartmut Holzgraefe hartmut@php.net lead shane Shane Caraveo developer shane@caraveo.com colin Colin Viebrock developer colin@easydns.com wez Wez Furlong developer wez@php.net The calendar extension presents a series of functions to simplify converting between different calendar formats. The intermediary or standard it is based on is the Julian Day Count. The Julian Day Count is a count of days starting from January 1st, 4713 B.C. To convert between calendar systems, you must first convert to Julian Day Count, then to the calendar system of your choice. Julian Day Count is very different from the Julian Calendar!
