# What Year Is It Without Leap Year

**Calendar is really a system to note some time these kinds of since the illustration.**

**What year is it without leap year**.
I know what youre thinking what about the year 2000.
A year is normal unless it is evenly divisible by 4 in which case it is a leap year.
Formula to determine whether a year is a leap year.

Leap years occur every four years and years that are evenly divisible by four 2020 for example have 366 days. For example the following is the complete list of leap years for the 21st century from year 2001 to 2100. The number of days in a year without including weekends totals 260 days.

Every four years this number will be 261 because of leap year such as in 2020. In both cases a day is 86400 s long unless a leap second has been declared by the BIPM. Leap Years are any year that can be exactly divided by 4 such as 2016 2020 2024 etc except if it can be exactly divided by 100 then it isnt such as 2100 2200 etc.

The year is multiple of 400. Its a leap year if year not 4 0. If the tropical year was precisely 6 hours longer than a calendar year with 365 days we could use the Julian calendar which adds a leap day every 4 years without exception.

In this program we ask the user to enter the year then we check it for leap year. Every year that is exactly divisible by four is a leap year except for years that are exactly divisible by 100 but these centurial years are leap years if they are exactly divisible by 400. The year is a leap year it has 366 days.

But 1900 1800 and 1700 were not. Leap years are necessary because the actual length of a year is nearly 36525 days not 365 days as commonly stated. That is a leap year has 366 days instead of 365 days.
