Formula for Converting
The factor for converting months to weeks is 4.348125, so 1 month is equal to 4.348125 weeks:
One mo = 4.348125 wk
We multiply three by the conversion factor to turn three months into weeks. It gives us the amount of time in weeks. We can also use a simple ratio to figure out the answer:
One mo → 4.348125 wk
Three mo → T (wk)
Solve the above ratio to find out how long T will take in weeks:
T(wk) = 3 mo × 4.348125 wk
T(wk) = 13.044375 wk
What happens in the end is:
Three mo → 13.044375 wk
We can say that three months are the same as 13.044375 weeks because:
3 months = 13.044375 weeks
How Many Weeks Does a Month Have?
Most countries use the Gregorian calendar. It demonstrates that there are exactly 365 days in a calendar year (except for leap years which have 366 days). These days are broken down into 12 months, and each month has either 31 or 30 full days in it.
It aids us in calculating the number of weeks in a month. There are 52 weeks and one day in a year since there are sevenday weeks.
Table of Weeks in a Month
Count how many weeks there are in each of the 12 months in a year. To figure out how many weeks there are in a month, we need to count the number of days and divide by seven. (1 week = 7 days).
Let’s look at the table below, which tells us how many weeks and days are in each month of the year. The table of weeks in a month helps us plan events better.
Month  Days  Weeks 

January  31 days  Four weeks + 3 days 
February  28 is a day (regular year), 29 days (leap year)  Four weeks, 
March  31 days  Four weeks + 3 days 
April  30 days  Four weeks + 2 days 
May  31 days  Four weeks + 3 days 
June  30 days  Four weeks + 2 days 
July  31 days  Four weeks + 3 days 
August  31 days  Four weeks + 3 days 
September  30 days  Four weeks + 2 days 
October  31 days  Four weeks + 3 days 
November  30 days  Four weeks + 2 days 
December  31 days  Four weeks + 3 days 
How Can We Tell If a Year Is a Leap Year or Not?
We split the year into four to establish if it is a leap year. If the year is divisible by 4, it is a leap year. Because it is divisible by four, the year 2020 features a February with exactly 29 days.
A Century Year
All regular years follow the rule above, but century years like 300, 700, 1900, 2000, and many others must be divided by 400 to see if they are leap years or not. For example, 2000 is divisible by 400, meaning it is a leap year.
But a century like 1900 is not divisible by 400, so it is not a leap year, even though it is divisible by 4.
Interesting Facts About Leap Year

Why does February get an extra day every four years? It is called a “leap year.”

The earth goes around the sun every 365 and a quarter days.

Most people only count 365 days a year, leaving out the quarter.

You get one extra day every four years when you add up the four quarters (1/4 + 1/4 + 1/4 + 1/4 = 1).

In a leap year, this day is added. Because of this, a leap year has 366 days.
Summary
Each month has 30 or 31 days, four weeks, and 2/3 days. Three months is 12 weeks and 6/9 days, or about 13 weeks. The moon doesn’t have a month for four weeks if it doesn’t have 28 days (except in February).
