The fact that the lunar phases repeat on the same solar dates about every 19 years (the Metonic cycle) can be used to keep lunar calendars approximately synchronized with solar calendars.
This is further explained below.
Generally, In contrast to solar calendars, which base their yearly cycles exclusively directly on the solar year, a lunar calendar is one that is based on the monthly cycles of the Moon's phases.
The Gregorian calendar, which is the one that is used now more than any other, is a solar calendar system that was initially derived from a lunar calendar system.
When the strategy of coordination is the intercalation of the 13th lunar calendar in a scheduled year from time to time, the Metonic cycle is the most accurate cycle of time less than one hundred years for coordinating the tropical year and the lunar month. The Metonic cycle has a duration of fewer than one hundred years.
In conclusion, It is possible to maintain lunar calendars nearly synced with solar calendars by making advantage of the fact that the lunar phases recur on the same solar dates about every 19 years. This phenomenon is known as the Metonic cycle.
