The Purpose of Leap Years
The main reason for having leap years is to ensure that our calendar aligns with the tropical year - the time it takes for the Earth to complete one orbit around the sun. The tropical year is approximately 365.2422 days, which is why leap years are necessary. By adding an extra day every four years, we can compensate for the fraction of a day that exists in our calendar year.

Understanding Leap Year Calculation
But how do we determine which years are leap years? The rule is quite simple: any year that is evenly divisible by 4 is a leap year, with the exception of century years (years ending in 00). However, if a century year is divisible by 400, it is still a leap year. This rule prevents an excessive number of leap years and keeps our calendar system in check. For example, 1900 was not a leap year because it is a century year that is not divisible by 400.
Interesting Facts about Leap Years
Leap years have captured our imagination for centuries, and there are several interesting facts surrounding them:
The concept of leap years dates back to ancient times. The ancient Egyptians were one of the first civilizations to adopt a leap-year system, adding an extra month to their calendar once every four years.
The reason we have an extra day in February during leap years is due to the influence of Julius Caesar. In 45 BCE, he introduced the Julian calendar, which added an extra day to February every four years. This system was in use until it was refined by Pope Gregory XIII in 1582, leading to the creation of the Gregorian calendar that we still use today.
Have you ever wondered why February has only 28 or 29 days? Well, the origin of this can be traced back to the Roman calendar. February was the last month of their original calendar, which had ten months in total. When January and February were added at the beginning, February's length was adjusted to ensure the total number of days in a year remained consistent.
If you were born on February 29, then you are known as a "leapling" or a "leaper." Since February 29 occurs only once every four years, leaplings often celebrate their birthdays on either February 28 or March 1 during non-leap years.
Leap Years in the Future
Looking ahead, we can also identify some leap years in the coming years:

2032
2036
2040

It's always interesting to think about the future and how these leap years will intertwine with important events and celebrations in our lives.
