>From http://en.wikipedia.org/wiki/0_(year): "Year zero" does not exist in the widely used Gregorian calendar or in its predecessor, the Julian calendar. Under those systems, the year 1 BC is followed by AD 1. However, there is a year zero in astronomical year numbering (where it coincides with the Julian year 1 BC) and in ISO 8601:2004 (where it coincides with the Gregorian year 1 BC) as well as in all Buddhist and Hindu calendars. -- View this message in context: http://forum.world.st/Which-calendar-does-Pharo-officially-use-tp3323638p3323638.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
