A 'Leap Year' occurs every four years.
To find a Leap Year, the year number must be divisble by '4'.
2020 / 4 = 505 so is a leap year.
2021 / 4 = 505.25 So NOT a leap year
2022 / 4 = 505.5 So not a leap year
2023 / 4 = 505.75 ~So not a leap year
2024 / 4 = 506 - so is a leap year.
et.seq.
NB The Earth orbits the Sun in 365.24 days. The ' -.24' is nearly a quarter of a day. So four quarters makes one whole day, so that one whole day is added every four years. However, the '-.24 - -0.25 = 0.01 ' So there is still a one hundredth of a day to account for. This is 14.4 minutes, so about once every 25 years a leap year is missed in order to account for this differential.
Remember the old verse:-
Thirty days hath September ,
April, June and November.
All the rest have thirty one,
Excepting February alone,
Which has 28 days clear,
And 29 days each Leap Year.
There were 24 leap years in that period:185218561860186418681872187618801884188818921896190419081912191619201924192819321936194019441948
Earth rotates roughly 365 and 1/4 times in a year, the extra 1/4 results in an extra day every 4 years, or a "leap year".
February is the shortest month out of 12 months.
The exact length, in days, of Earth's true sidereal orbital period is 365.256366 (364 and 1/4 ) days or 1.0000175 years. As this is not a whole number of days, our Earth calender is arranged to have normal years and leap years. We make a normal year have 365 days and a leap year have 366 days. We arrange it so that a leap year happens every 4th year so that extra day makes up for the four 1/4 days we need make the orbit position the same over time.
A year on Earth is about 365.24 days long. Most years are 365 days, and leap years have 366 days.
24 leap years
There were 4 & 3/4 leap years between 1994 and 2011.
There are 13 leap years during that period:2000200420082012201620202024202820322036204020442048
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.
Between 1962 and 2011, there were 12 leap years: every four years from 1964 through 2008 inclusive.
There were 10 leap years between 1970 and 2011.

Between 2002 and 2011 the leap years were 2004 and 2008.
there were 200 years between ice ages, there were 201 when it ended on a leap year.
