Months of the Year

Original Roman calendar had 10 months, beginning in March and ending in December

Original Roman calendar was revised by Julius Caesar in 45 BC; he was helped by Sosigenes (an astronomer); he added two months to the calendar (January and February); he changed the names of two months - Quintilis became Iulius and Sextilis became Augustus; he also created the idea of a leap year

There were three fixed dates on the Roman calendar:

     Kalends - 1st day of the month

     Nones - 5th day of the month; 7th day in March, May, July, and October

     Idus / Ides - 13th day of the month; 15th day in March, May, July, and October
