Everything about Year zero
Year used in some calendars
A year zero is a date where the current year for a given calendar system is zero. In systems which include a year zero, this year would be the epoch. Year zero does not exist in the Anno Domini (AD) calendar year system commonly used to number years in the Gregorian calendar and Julian calendar. Instead, AD 1 is treated as the epoch, so that the year 1 BC is followed directly by year AD 1. However, there is a year zero in both the astronomical year numbering system, and the ISO 8601:2004 system, a data interchange standard for certain time and calendar information. There is also a year zero in most Buddhist and Hindu calendars. Wikipedia →
