12 months are used instead of 13 in most calendars because it aligns more closely with Earth's orbit around the Sun, which takes approximately 365.25 days. Twelve months can be divided into smaller units evenly, making it easier for calendrical structures. Including 13 months would create inconsistent month durations, complicating timekeeping.
