Leap years have a long history dating back to ancient civilizations! ๐
The ancient Egyptians were among the first to use a calendar that included a leap day around 4,000 years ago. In 46 BCE, Julius Caesar introduced the Julian calendar, which had a leap year every four years. Later, in 1582, Pope Gregory XIII updated the calendar, creating the Gregorian calendar we still use today. ๐
This new system fixed the leap year rules, allowing us to keep track of time more accurately! Thanks to these smart people, we can enjoy our extra day every four years! ๐
