How Many Weeks in a Month
It was the Babylonians, who lived in modernday Iraq and decided that our weeks would be seven days long. They were accurate observers and interpreters of the heavens, and they adopted the number seven because they had observed seven celestial bodies: the Sun, the moon, Mercury, Venus, Mars, Jupiter, and Saturn. Hence, this number was significant for them.
We all depend on the calendar for it as it helps us time ourselves every day. Check out how many weeks are there in a month in this lesson and get a better idea of how you can manage your tasks in time with such easy calculations of days and weeks, and meet your targets before the deadline.

How Many Weeks are there in a Month?
Have you ever thought about how the calendar works and helps us time ourselves every day? The Gregorian calendar, the most widely used calendar in the world, shows that there are 365 days in a year (except for leap years which have 366 days). These days are grouped into 12 months where each month has either 31 days, 30 days, or 28 days, helping us find the weeks per month. The days are grouped together as 7 day weeks, so, one year has 52 weeks + 1 day.
Number of Weeks in a Month
All the months in the calendar have 4 complete weeks because every month has at least 28 days. A few months have some extra days, but they are not counted as a week because these extra days are not enough, to sum up to 7 days (1 week = 7 days).
Hence, it can be said that on average, 1 month = 4 weeks and 2 days, or 1 month = \(4\frac{1}{3}\) weeks.
Calculation of Number of Weeks in a Month
We can easily count the number of weeks in a month using the following steps:
 Step 1: Count the number of days in the month.
 Step 2: Divide the number of days in the month by 7.
For example, the month of August has 31 days (1 week = 7 days). Thus, 31/7= 4 weeks + 3 days. This shows 4 full weeks + 3 days.
Weeks in a Month Table
Observe the number of weeks in the 12 different months of a year. In order to calculate the number of weeks in a month, we need to count the number of days in the month and divide that number by 7(1 week=7 days). To be precise, let's have a look at the table given below, which shows the exact number of weeks and days in each month of the year. Weeks in a month table helps us to plan events in a better way, be it trips or even exam schedule.
Month  Days  Weeks 

January  31 days  4 weeks + 3 days 
February 
28 days (regular year) 29 days (leap year) 
4 weeks 4 weeks + 1 day 
March  31 days  4 weeks + 3 days 
April  30 days  4 weeks + 2 days 
May  31 days  4 weeks + 3 days 
June  30 days  4 weeks + 2 days 
July  31 days  4 weeks + 3 days 
August  31 days  4 weeks + 3 days 
September  30 days  4 weeks + 2 days 
October  31 days  4 weeks + 3 days 
November  30 days  4 weeks + 2 days 
December  31 days  4 weeks + 3 days 
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.
Interesting Fact:
Why does February have an extra day after every 4 years, which we call a leap year?
 The earth takes 365 and a quarter day to go around the sun.
 An ordinary year is taken as 365 days only, leaving the quarter.
 The four quarters are added together ( 1/4+1/4+1/4+1/4=1 ) to make an extra day every four years.
 This day is added to the leap year. Therefore, there are 366 days in a leap year.
Solved Examples

Example 1: Calculate the number of weeks for the month of March 2020.
Solution:
The month of March has 31 days. Divide 31 by 7: 31/7= 4 weeks + 3 days (because 1 week = 7 days). Thus, we get 4 weeks and 3 days.
Therefore, March has 4 weeks + 3 days.

Example 2: What is the date today if tomorrow is March 1^{st} and it is not a leap year?
Solution:
If it is not a leap year, then February has 28 days. February is followed by March and the last day of February is 28^{th}. Thus, if tomorrow is March 1^{st}, today is February 28
Therefore, Today's date is February 28.

Example 3: Tom's mother told him there are 3 weeks and 4 days left in the year to end. Can you help him understand how many days are left in the year?
Solution:
Tom's mother said that the year will end in 3 weeks and 4 days. 3 weeks = 21 days. Thus, 21 days + 4 days = 25 days
Therefore, the total number of days left in the year to end is 25.
