A year has 12 months. It starts with the month of January and ends with the month of December. It is very important to remember the number of days in a month. There are months with 31 days, 30 days, and even with 28/29 days. Let's have look at the table given below:
January  31 days 
February  28/29 days 
March  31 days 
April  30 days 
May  31 days 
June  30 days 
July  31 days 
August  31 days

Leap Year
A Leap year is a year when an extra day, referred to as a leap day(February 29) is added to the shortest month, February. To keep our calendar in alignment with the Earth's revolutions around the Sun, leap days are needed. The Earth takes approximately 365.242189 days or 365 days, 5 hours, 48 minutes, and 45 seconds – to complete one revolution around the Sun referred to as a tropical year.
A leap year has 366 days instead of the usual 365 days and occurs almost every four years.
How do we know whether a year is a leap year?
Divide the year by 4. If it is fully divisible by 4, it is a leap year. For example,2020 is divisible by 4, thus it is a leap year with a February of 29 days.
An Exception to the rule: A Century Year!
Century years like 300, 700, 1900, 2000, and many like these need to be divided by 400 to check whether they are leap years or not. For example, a century year like 2000 is divisible by 400, so it is a leap year. However, a Century year like 1900 is not divisible by 400, thus it is not a leap year, even though it is divisible by 4.
Important Points
 A normal year is equal to the time taken by Earth to complete one orbit around the Sun. Numerically, it is equal to 365 days and 6 hours.
 In the period of 4 years, 6 hours becomes 24 hours = 1 extra day.
 This extra day added to the calendar once every four years to form a leap year of 366 days.
