Why does it take so long for the earth to have a leap year?
"Leap Year" is a human invention. We made it up in order to keep our calendar in sync with the seasons. The seasons take 365 and 1/4 days to repeat. But if we tried to put a quarter-day in our calendar, things would really get seriously messed up. So instead of putting an extra quarter-day in the calendar every year, we put an extra whole day in it every fourth year, which is exactly the same thing. If we didn't do that, then each season would creep 25 days earlier every century. If Winter (in the northern Hemisphere) started on the correct date at the time of the American Revolution, then by now, Winter would be starting on October 26 instead of December 21.

Why is the calendar divided into 12 months?
Because Our calendar is a product of long evolution from a hunting society to an agricultural society. The hunters originally used a lunar calendar--new month each new moon. But new moons occur every 29.5 days, which is 12 in 355 days. This is not commensurable with a seasonal calendar such as agricultural societies would want. Ancient Rome tried to fix this by having a 13th month every third year. This did not work out too well, because the head priests played games, calling for an extra month whenever people they liked were elected to head the government (2 year terms). Julius Caesar hired an ethnic Greek from Alexandria Egypt, Sosigenes, to create the 365 day calendar with an extra day every fourth year.12 month calendars are favored because business works on a quarter system.
Which was a calendar not followed by the Ancient Egyptians?

Their calendar was primarily designed to regulate agricultural activities and religious festivals, reflecting the importance of the Nile's annual flooding cycle.
