### Why was 1900 not a leap year?

There is a leap year every year whose number is perfectly divisible by four - except for years which are both divisible by 100 and not divisible by 400. The second part of the rule effects century years. For example; **the century years 1600 and 2000 are leap years, but the century years 1700, 1800, and 1900 are not**.

there is an exception. If the year is also divisible by 100, it is not a Leap Year unless it is also divisible by 400. Therefore **2004, 2008, 2012, 2016** were all Leap Years. While 2000 was a Leap Year, 1900 was not a Leap Year and 2100 will not be one either.

The rule is that **if the year is divisible by 100 and not divisible by 400**, leap year is skipped. The year 2000 was a leap year, for example, but the years 1700, 1800, and 1900 were not. The next time a leap year will be skipped is the year 2100.

The rule is that **if the year is divisible by 100 and not divisible by 400**, leap year is skipped. The year 2000 was a leap year, for example, but the years 1700, 1800, and 1900 were not. The next time a leap year will be skipped is the year 2100.

#### The Science Of Leap Year

The rule is that **if the year is divisible by 100 and not divisible by 400, leap year is skipped**. The year 2000 was a leap year, for example, but the years 1700, 1800, and 1900 were not. The next time a leap year will be skipped is the year 2100.

The rule is that **if the year is divisible by 100 and not divisible by 400**, leap year is skipped. The year 2000 was a leap year, for example, but the years 1700, 1800, and 1900 were not. The next time a leap year will be skipped is the year 2100.

To be a leap year, the year number must be divisible by four except for end-of-century years, which must be divisible by 400. This means that the year 2000 was a leap year, although 1900 was not. **2020, 2024 and 2028 are all leap years.**

**if the year is divisible by 100 and not divisible by 400**, leap year is skipped. The year 2000 was a leap year, for example, but the years 1700, 1800, and 1900 were not. The next time a leap year will be skipped is the year 2100.

#### The Science Of Leap Year

For this reason, **not every four years is a leap year**. The rule is that if the year is divisible by 100 and not divisible by 400, leap year is skipped. The year 2000 was a leap year, for example, but the years 1700, 1800, and 1900 were not. The next time a leap year will be skipped is the year 2100.

For this reason, **not every four years is a leap year**. The rule is that if the year is divisible by 100 and not divisible by 400, leap year is skipped. The year 2000 was a leap year, for example, but the years 1700, 1800, and 1900 were not. The next time a leap year will be skipped is the year 2100.

A year may be a leap year if it is evenly divisible by 4. Years that are divisible by 100 (century years such as 1900 or 2000) cannot be leap years unless they are also divisible by 400. (For this reason, the years 1700, 1800, and 1900 were not leap years, but the years 1600 and 2000 were.)

**A year is a leap year if it is evenly divisible by four (4), unless it is a century year** (eg. 1900, 2000, etc) when it is a leap year only if the year is evenly divisible by 400.

#### How Many Leap Years Are There From 1850 To 2050?

For example, the years 1700, 1800, 1900 are **not leap years**, but the years 1600 and 2000 are leap years.

**A year is a leap year if it is evenly divisible by four (4), unless it is a century year** (eg. 1900, 2000, etc) when it is a leap year only if the year is evenly divisible by 400.

Therefore, the year 2000 will be a leap year, but the years 1700, 1800, and 1900 were not. 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**.
