That's VERY cool, and something I didn't know. The Ancient Egyptians had a solar calendar that was also pretty accurate. Moslems use a lunar calendar if I remember correctly.
Except that the moon cycles ~29.5 days, so a lunar month is 29 or 30 days. 29.5x12= 354, 29.5x13= 383.5. It doesn't really come close to an even solar year. Unless you're one of those people that thinks math is racist.
The Roman calendar is strictly solar, to the point where the months have lost their natural tie to the moon. Traditionally, a new moon = new month. Same root word.
The Muslim calendar is strictly lunar, so the months are synced to the moon but the year has lost it's tie to the sun. They can't have regular seasonal holidays by their calendar as a date that is in spring one year will be in the fall in a couple decades.
The Jewish calendar is in the middle. True lunar months, and leap years to keep seasons aligned. The original way of identifying leap years was tied to farming: the crops are expected to be ready to harvest in the month of Adar. If they aren't ready for harvesting it's time for a leap year, so they'd just repeat the month have Adar 2.
