Number of Days in a Month
The ancient Romans started with a calendar of 10 months. In the original Roman calendar, the months were named as Martius, Aprilis, Maius, Junius, Quintilis, Sextilis, September, October, November, and December. In this calendar, around 60 days were left that were unaccounted. Later, the months Januarius and Februarius were added to the end of the year considering the remaining extra 60 days.

How to Remember the Days of a Month?
The number of days in a month need to be memorized. We should keep in mind that we have months with 31 days, months with 30 days, and a month which has 28 or 29 days. The following method helps us remember these months along with the number of days that they have.
Knuckle method
The knuckle method uses the knuckles of our hands and is a simple trick that helps us remember the number of days in a month. Let us see how it works.
 The months that are on the top of the knuckle represent 31 days, whereas, the depression between the knuckles represents the months that have 30 days.
 We start with January on the knuckle, so February comes in the depression, March comes on the knuckle and April comes in the depression, and so on.
 It should be noted that the two knuckles where your hands meet denote July and August which have 31 days.
 The last knuckle is not used.
 Now, let us check, March is on the knuckle, so it has 31 days. But April is not on the knuckle, so it has only 30 days.
What is a Leap Year?
A normal year has 365 days. In a normal year, the Earth takes about 365.242375 days to go around the Sun, but we count only 365 times. In other words, our earth takes 365 and a quarter days to complete one revolution. So, in an ordinary year, we take 365 days, leaving the quarter. These 4 quarters sum up to make 1 extra day after every 4 years. This extra day is then added to the leap year. This is the reason why there are 366 days in a leap year.
