To calculate weeks in a year, divide the total number of days in the year by 7 (the number of days in a week). For a regular year, the calculation is 365 days / 7 = 52.14 weeks. For a leap year, with 366 days, it's 366 / 7 = 52.29 weeks. This approximation accounts for the extra day in leap years, keeping the calculation straightforward and easily understandable.
