New Year’s Day was celebrated for the first time when the Julian calendar took effect. In designing his new calendar, Caesar enlisted the aid of Sosigenes, an Alexandrian astronomer, who advised him to do away with the lunar cycle entirely and follow the solar year, like the Egyptians. The year was calculated to be 365 and 1/4 days, and Caesar added 67 days to 45 B.C., making 46 B.C. begin on January 1, rather than in March.
