  2. Feb 17, 2020 · Leap Year exists because of the time it takes the Earth to orbit the Sun. There are 365 days in most calendar years, but in the time it takes for the Earth to go around the sun once, our planet actually spins 365 and nearly a quarter times. The reason we care about that extra quarter is because the Earth has seasons.

    As I was growing up one of my best friends was born on a leap year. The joke in our school was that while the rest of the class were excited to turn eight, he was stuck at two years old. The situation used to perplex me. While he was certainly immature in many ways, he was by all logic and measurements, not a 2-year old. We drifted as we went into ...

The extra day ...

    Adding days to a calendar is a technique called ‘intercalation.’ It’s used in timekeeping to align the calendar to the seasons or moon phases. Now we’re beginning to get to the problem. Leap years are a technique to fudge the inaccuracies of the Gregorian calendar with the position and motion of the sun and moon. The problem is that a year isn’t ex...

    The Gregorian Calendar was instated by Pope Gregory XIII in 1582. He designed it to fix the problems in the Julian Calendar. In its time of use, the Julian Calendar was found to drift considerably from the solar years. 1 day every 128 years. The calendar spaces leap years to make the average year 365.2425 days long. The spacing is made to prevent t...

    The Gregorian calendar adds extra rules to reduce the inaccuracy in the Julian calendar. For every year divisible by 100, it’s not considered a leap year. That means 1900 was not a leap year. The exception to the rule is that if the year is also divisible by 400, then it IS a leap year. For example, 2000 was a leap year. The extra rules added to th...

    Today the Gregorian Calendar is the most popular system used across the world. Ancient calendar systems, including the Greek Sothic cycle, would calibrate when the year started against a background star reference of Sirius. The Egyptians also chose Siriusas the starting point for the Nile-Lunar calendar. Other ancient civilizations used astronomica...

    The Gregorian Calendar system is flawed. When we see the leap-year paradox, it reveals ancient techniques to account for this was to calibrate the solar year with background star references. Today, it’s easy to forget the origins of our calendar system. Leap years are an essential testament to the lost knowledge of earth as part of a larger cosmic ...

  4. The Gregorian calendar's predecessor, the Julian Calendar, was replaced because it was too inaccurate. It did not properly reflect the actual time it takes the Earth to orbit once around the Sun, known as a tropical year. Realigned With the Sun. The Julian calendar's formula to calculate leap years produced a leap year every four years.

  5. The standard calendar followed around the world is the Gregorian calendar. It has 12 months with 30 or 31 days out of which February is the only month that has 28 or 29 days. If there are 29 days in a year, it is called a 'leap year'. This Buzzle article provides a list of leap years from the year 1800 to 2400.

  6. It’s not—it means you were born on a leap day. Leap days are important because they help our calendar match up with the same seasons every year. Human-made calendars generally have 365 days; the solar, or tropical, year that influences seasons is about 365.2422 days long. (A solar year is how long it takes the Earth to revolve around the sun.)
