Why Are There 52 Weeks in a Year and Not 48

A year consists of 52 weeks because it is based on the Earth’s orbit around the Sun, which takes approximately 365.25 days to complete. A week, by convention, has 7 days, so dividing the 365 days of a year by 7 gives roughly 52.14 weeks. While this isn’t an exact number, it results in a calendar year of 52 full weeks plus an extra day (or two days in a leap year). The idea of 48 weeks would only account for 336 days, falling short of a full year by about 29 days. Thus, the 52-week structure aligns better with the solar year.
