When Julius Caesar consolidated Roman power in the mid 1st century BC, he had an opportunity to correct the long neglected Roman Calendar. Consulting Egyptian astronomers, Caesar altered the Republican calendar by basing it on a solar, rather than lunar, cycle. Adding 10 days to the permanent calendar and a couple of months at the end of 46 BC, the new Julian Calendar was back in sync with the seasons. Additionally a calendar chart is also available Julian Calendar Overview.
