Julius Caesar introduced leap years when he reformed the Roman calendar in 46 BCE. His calendar, which is called the Julian calendar, was in use for almost 20 centuries. Beginning in 1582, it was eventually replaced by the Gregorian calendar, which is almost identical to the Julian calendar but is more accurate because it has fewer leap years.

No, but 2004 and 2008 were both leap years.
The Mayan civilization is generally considered to have flourished from around 250 AD to 900 AD. Leap years, defined by the Gregorian calendar as years divisible by 4 (with some exceptions), began in 1582 when the calendar was introduced. Since the Mayan civilization ended in 900 AD, there have been approximately 1,123 leap years from that time until 2023, assuming we consider leap years from 900 AD onward.
Leap Years are years divisible by four, with two exceptions. 1. "Century" year numbers (divisible evenly by 100) are not leap years. 2. Years divisible evenly by 400 ARE leap years. So years like 1992 and 1996 were leap years. Century years like 1900 or 2100 are NOT leap years. But 2000 was a leap year, and 2400 will be.
The Julian calendar introduced by Julius Caesar had 365 days per year and 366 EVERY 4 years. This had allowed the calendar to creep out of line with the seasons. The Gregorian calendar we use now has the leap year rule: Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100; the centurial years that are exactly divisible by 400 are still leap years. For example, the year 1900 was not a leap year; the year 2000 was a leap year.
There are 4 years between every leap year. Correction: There are 4 years between MOST leap years. That's the case 99.25% of the time. For the other 0.75% of the time, there are 8 years between leap years.
Leap years are US election years. 2006 was not a leap year.
The Leap Years was created in 2008.
There were 24 leap years in that period:185218561860186418681872187618801884188818921896190419081912191619201924192819321936194019441948
Leap years are years that are multiples of 4; the next leap year is 2012.
Leap year is when there is an extra day in the month of February. The next leap years are 2016, 2020 and 2024.
Leap years are:Divisible by 4 except for centenary years which are leap years if divisible by 4 but not 400.1947 is not centenary year and not divisible by 4It is not a leap year
