Exploring Leap Years In The 21St Century

To determine the number of leap years in the 21st century, we need to identify the years that are divisible by 4, with the exception of those divisible by 100 but not by 400. In the first half of the 21st century, which spans from 2000 to 2049, the leap years are as follows: 2000, 2004, 2008, 2012, 2016, 2020, 2024, 2028, 2032, 2036, 2040, 2044, and 2048. These leap years occur every four years, with exceptions made for those divisible by 100 but not by 400, ensuring the accuracy of our calendar system. Therefore, there are a total of 13 leap years in the first half of the 21st century.

In the 21st century, leap years occur every four years, with an extra day added to February, making it 29 days instead of the usual 28. The last leap year in the 21st century was 2096. To clarify, here’s a complete list of leap years in the 21st century, starting from the year 2001 and ending in 2100: 2004, 2008, 2012, 2016, 2020, 2024, 2028, 2032, 2036, 2040, 2044, 2048, 2052, 2056, 2060, 2064, 2068, 2072, 2076, 2080, 2084, 2088, 2092, and finally, 2096. These leap years ensure that our calendar remains synchronized with the Earth’s orbit around the sun.

How many leap years occur within a century? A century spans 100 years, during which there are 24 leap years, each consisting of 366 days, and 76 non-leap years, each lasting 365 days. To determine if a year is a leap year, it must be divisible by 4, but there is an exception. A year divisible by 100 is a leap year only if it’s also divisible by 400. Therefore, in most cases, there will be 24 leap years in a century.
