Year zero facts for kids

Kids Encyclopedia Facts

Year zero does not exist in the Anno Domini (AD) system usually used to number years in the Gregorian calendar and Julian calendar. In this system, 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.
