An anomalistic month is longer than a sidereal month because the perigee moves in the same direction as the Moon is orbiting the Earth, one revolution in nine years.
Therefore, the Moon takes a little longer to return to perigee than to return to the same star.
This system has been used for hundreds of years and throughout many generations.
This calendar is cyclical and relies on the position and shape of the moon.
