The full moon It is a phenomenon that usually occurs only once a month, but a year has a total of 365 or 366 days depending on whether it is a leap year or not and about 12.4 lunations, since each phase of the moon lasts approximately 7 days and the moon goes through 4 phases -full moon, new moon, waxing quarter and waning quarter-. To complete this cycle takes approximately 28 days.

Thus, depending on the fit of the lunar cycles in the calendar, there can be years in which there are 12 full moons and years in which there have been or will be 13, as is the case of 2023, which will have two full moons in August: the 1st and the 31st.
