Of course, a 355-day calendar had its bugs. After a few years went by, the seasons and months would fall out of sync. So to keep things straight, the Romans would occasionally insert a 27-day leap month called Mercedonius. The Romans would erase the last couple days of February and start the leap month on February 24—further evidence no one ever cared much for the month. This caused headaches everywhere. The leap month was inconsistent, mainly because Rome’s high priests determined when it would arrive. Not only did they insert Mercedonius haphazardly, but the priests (being politicians) abused the power, using it to extend the terms of friends and trim the terms of enemies. By Julius Caesar’s time, the Roman people had no clue what day it was.So Caesar nixed the leap month and reformed the calendar again. (To get Rome back on track, the year 46 BCE had to be 445 days long!) Caesar aligned the calendar with the sun and added a few days so that everything added up to 365. February, which by now was at the top of the calendar, kept its 28 days. We can only imagine it’s because Caesar, like everyone before and after him, just wanted it to be March already.
