About This Conversion
Weeks to months has no exact answer, because months are not a whole number of weeks. This converter uses the average Gregorian month of 30.44 days, which is a 365.2425-day year divided by twelve, so four weeks is 0.92 months rather than a clean one.
That gap compounds. Thirteen four-week cycles fit in a year, not twelve, which is why a payroll run every four weeks produces thirteen payments some years and why "six weeks" and "a month and a half" are not the same period. For pregnancy, contracts and notice periods, count the actual calendar dates rather than converting.
