Historical Context
The 12-month calendar system we use today has ancient origins. Before 700 BCE, the Roman calendar consisted of only 10 months totaling 304 days. The calendar began in March and ended in December.
January and February were later added to the calendar (bringing it to 355 days). In 45 B.C., Julius Caesar introduced the Julian calendar with 12 months and the concept of a leap year, establishing the system that forms the basis of our modern calendar.
