Short Answer 
Each month contains at least 4 weeks, but the total number of weeks and extra days varies depending on the month. Most months have either 30 or 31 days, resulting in 2 or 3 extra days respectively, while February usually has 28 days. A standard year consists of 52 weeks and approximately 1 additional day, totaling 365 days, with leap years having 366 days.
Step 1: Understanding Weeks in a Month
Each month consists of at least 28 days, which ensures that there are always 4 full weeks contained within it. However, as months vary in length, most months include additional days beyond the basic four weeks. This means that while every month contains 4 weeks, they may also have extra days that change based on the month.
Step 2: Monthly Day Breakdown
Months differ in the number of days they contain, affecting the total weeks and extra days. The breakdown is as follows:
- Months with 30 days (April, June, September, November) have 4 weeks and 2 extra days.
- Months with 31 days (January, March, May, July, August, October, December) contain 4 weeks and 3 extra days.
- February has 28 days generally, which comprise 4 weeks, and in a leap year, it gains an additional day, totaling 29 days.
Step 3: Yearly Total Weeks and Days
Despite common perceptions, a standard year has 52 weeks and a few extra days, totaling 365 days. This can be calculated by:
- Recognizing that 12 months provide 48 weeks (4 weeks x 12 months).
- Accounting for the approximately 29 extra days found in a year translates into 4 weeks and 1 day when calculating.
- In a leap year, February adds one extra day, bringing the total to 366 days.
