The moon's 29.5 day synodic month was the basis of lunar calendars throughout the course of history. While a lunar calendar was convenient, it presented an immediate challenge: Compared to the solar year of 365 days, a lunar year lasts an average of 354 days. Some groups decided to ignore this discrepancy.
Each phase lasts for only an instant as the moon is constantly moving. For example, to the naked eye, the full moon lasts several days, however, technically, it is a full moon for just an instant before it begins to wane. The moon takes just less than one month -- an average of 29.5 days to complete its phases.
