Although, the Gregorian calendar was decreed in 1582, Great Britain and its colonies promulgated the Gregorian calendar in 1752, by which time it was necessary to correct by 11 days. For example, Saudi Arabia adopted the Gregorian calendar for the purpose of paying public sector staff effective 1 October 2016; private sector employers had already adopted the Gregorian calendar for pay purposes. Countries which have not adopted the Gregorian calendar are Ethiopia, which uses the Ethiopian calendar, Nepal follows the Vikram Samvat, Iran and Afghanistan use the Solar Hijri calendar. Israel follows the Hebrew calendar and Myanmar the Burmese calendar, while some countries use a modified version of the Gregorian calendar, including Thailand (Thai solar calendar), Japan (Japanese calendar), North Korea (North Korean) and China uses the Chinese calendar, which is lunisolar. September 14 is commemorated as the promulgation of the Gregorian Calendar, now widely in use.
