The Roman Calendar
Attributed to Romulus, the Roman calendar originally had only ten
months, common among `primitive` agricultural people. (They were apparently
unconcered about the passage of time during the winter months when it was
impossible to work in the fields.) At some later time (traditionally under Numa, 715-676BC), the calendar was reformed to include 12 months of 28 days, with an extra month to keep the calendar aligned with the sun. Julius Caesar, as Pontifex Maximus, reformed the calendar as of Jan. 1, 45BC, and introduced the calendar as we basically know it today, 12 months with varying days each, totaling 365 days a year with a leap year every 4 years.
