It's pretty easy to figure out if a year is a leap year. You just need to do a few very simple calculations.

Steps

1. 

   Start choosing the year you want to calculate.

2. 

   
   
   Calculates whether the year is divisible by 4 (the division result has no remainder). If it's not divisible by 4, for example, in 1997, the year isn't a leap year. If divisible by 4, such as 2012, read and work on.

3. 

   Divide the year by 100. A year is divisible by 4 but not 100, say 2012, not a leap year. If the year you calculate is divisible by both 4 and 100, like in 2000, do the same.

4. 

   
   
   Divide the year by 400. A year is divisible by 100 but not by 400, as in 1900, not a leap year. If it's divisible by both 100 and 400, that year is a leap. According to this calculation, the year 2000 was definitely a leap year. advertisement

Advice

• Leap years: 1600, 1604, 1608, 1612, 1616 ... 1684, 1688, 1692, 1696, 1704 (1700 was not profitable, you know the reason?), 1708, 1712 ... 1792, 1796, 1804 (the year 1800 was not profitable), 1808, 1812 ... 1892, 1896, 1904 (1900 was not profitable), 1908, 1912 ... 1992, 1996, 2000 (2000 was a leap year again, find out the reason is that right?), 2004, 2008, 2012 ... 2092, 2096, 2104 (year 2100 is not profitable) ... 2196, 2204 ... 2296, 2304 ... 2396, 2400 (same reason), 2404 ... etc.
• All years divided by 4 are leap years. A year has 365 days and 6 hours, or 365 and 1/4 days. Every four years, these 6 hours will add up to a day (6x4 = 24) and this is also the reason why every four years, February has a 29 day.
