2016 is going to be different from the last three years as it will have one extra day in the month of February. So, the month of February will have 29 days instead of normal 28 days. In other words, the year 2016 will have 366 days instead of normal 365 days. What is the reason behind this,? Why it that it comes ever four year only? How to find whether the specific year is the leap year or not.
Let’s try to find the answer of these questions. The secret of the additional day in the year lies in the time take by the earth to revolve around the Sun. As we all know that our earth revolves around the Sun and completes on revolution in 365 days and four hours. Four hours being one fourth of 24 hours that make up a day, it is not possible to adjust it every year. So, these four hours are allowed to get carried forward for four years so that the duration of 24 hours is completed. This is why the leap year comes every four years. Now how to find out if the particular year is the leap year. It is very simple because you have to divide the year by 4 and, if is completely divisible, then it’s a leap year. For instance, the current year 2015 is not a leap year because 2015 is not divisible by 4. On the other hand, 2016 is a leap year because 2016 is the multiple of 4. After 2016, the next leap year will be 2020.
