Is 2024 a leap year

As you’re nearing the end of February, dates can get confusing. The irregular month, already unique in its 28-day length, sometimes has a 29th day, also known as Leap Day.

This is even worse for the 5 million people with Leap Day birthdays, according to a History estimate, whose real birthdays come only once every four years.

This phenomenon may cause you a small inconvenience, but leap years are not just a cruel trick calendar companies play to keep you guessing. There’s actually a very good astronomical reason for the added day — but we’ll get into that later.

When is the next leap year?

Generally speaking, leap years come every four years: 2024, 2028 and 2032, for example, will all be leap years.

Usually, if a year is divisible by 4, that makes it a leap year, but this rule does not hold for years which are multiples of one hundred, according to History.com. Although the Earth’s orbit around the sun was previously thought to be 365.25 days, it actually takes closer to 365.24 days says History.com.

To fix this small discrepancy, century years which are not divisible by 400 are not leap years. The year 2000 was a leap year, but the year 2100 will not be.

Is 2024 a leap year

Why do we have leap years?

Because the amount of time the Earth takes to spin on its axis is not dependent on the amount of time the Earth takes to complete a full orbit around the sun, the number of 24-hour rotations that fit into a calendar year is not a whole number.

According to History, a leap year is the solution to this. Just one extra day every four years keeps our calendar lined up correctly with the orbit of the Earth, meaning winter stays winter, and summer stays summer.

How many days are in a leap year?

There are 366 days in a leap year — one more than the typical 365-day year.

When was the last leap year?

Until 2024, 2020 would have been the most recent leap year.

..., 2008, 2012, 2016, 2020, 2024, 2028, ... etc

Leap Year

  • A normal year has 365 days.
  • A Leap Year has 366 days (the extra day is the 29th of February).

How to know if it is a Leap Year:

Leap Years are any year that can be exactly divided by 4 (such as 2016, 2020, 2024, etc)
 
Is 2024 a leap year
except if it can be exactly divided by 100, then it isn't (such as 2100, 2200, etc)
    except if it can be exactly divided by 400, then it is (such as 2000, 2400)

Try it here:

Why?

Because the Earth rotates about 365.242375 times a year ...

... but a normal year is 365 days, ...

... so something has to be done to "catch up" the extra 0.242375 days a year.

So every 4th year we add an extra day (the 29th of February), which makes 365.25 days a year. This is fairly close, but is wrong by about 1 day every 100 years.

    So every 100 years we don't have a leap year, and that gets us 365.24 days per year (1 day less in 100 year = -0.01 days per year). Closer, but still not accurate enough!

    So another rule says that every 400 years is a leap year again. This gets us 365.2425 days per year (1 day regained every 400 years = 0.0025 days per year), which is close enough to 365.242375 not to matter much.

    So, Which Are and Which Aren't?

    So 2000 and 2400 are leap years but 1800, 1900, 2100, 2200 and 2300 are not.

    Apart from that, every year divisible by 4 (2012, 2016, 2020, 2024, etc.) is a leap year.

    How far away each year is from the average

    Is 2024 a leap year

    Example: look just before 2100, the worst year is 1.2 days ahead, but because 2100 is not a leap year they all get adjusted back by 1 day.

    So this keeps us pretty close, and any other adjustments can be done way in the future (when the Earth may be rotating a little slower, anyway!)

    Only since 1582 (Gregorian Calendar)

    These leap year rules were introduced in 1582 by the Gregorian Calendar, named after Pope Gregory XIII.

    (It replaced the old Julian Calendar by Julius Caesar that only has one rule of a leap year every 4th year, and is now about 13 days behind our current date.)

    Does Feb 2024 have 29 days?

    The next leap day is February 29, 2024. 2020 was also a leap year, so the last leap day was February 29, 2020.

    Is there 366 days in 2024?

    2024 is a leap year. The next leap day is February 29, 2024, on a Thursday.

    Is 2024 a leap year how many days?

    There are 366 days in a leap year, which is one day more than an average year which has 365 years. The extra day will be added in February, so instead of the usual 28 days of February there will be 29 days in February 2024.

    What are the next 5 leap years?

    The complete list of leap years in the first half of the 21st century is therefore 2000, 2004, 2008, 2012, 2016, 2020, 2024, 2028, 2032, 2036, 2040, 2044, and 2048.
