Julius Caesar's calendar reform in 45 BCE began the year on January 1. The tradition of starting the year in March continued in some countries for a long time. January 1 was only instituted as New Year's Day in France in 1564. Great Britain and her colonies continued to use March 25 until 1752, the same year they finally adopted the Gregorian calendar.In ancient Hellenic civilization, March was called Anthesterion. In old Japanese calendar, the month is called ''Yayoi'' (弥生). In Finnish, the month is called ''maaliskuu'', of obscure origin.
