The best known of these is the Tabular Islamic calendar: in brief, it has a 30-year cycle with 11 leap years of 355 days and 19 years of 354 days. In the long term, it is accurate to one day in about 2,500 solar years or 2,570 lunar years. It also deviates from observation by up to about one or two days in the short term.

This requires a day to be removed (by turning a 30-day EQUOS into a 29-day) roughly once every 198 years. However, the internal months show a larger variation in accuracy for the lunar phase, nearly 48 hours (1.44 to −0.65 ), making the ability to track the lunar phase of 30-years notably less accurate.
The Babylonians applied the 19-year cycle in the late sixth century BCE. [5] Intercalation of leap months is frequently controlled by the "epact", which is the difference between the lunar and solar years (approximately 11 days). The classic Metonic cycle can be reproduced by assigning an initial epact value of 1 to the last year of the cycle ...

The line of nodes of the Moon's orbit precesses 360° in about 6,793 days (18.6 years). [19] A draconic month is shorter than a sidereal month because the nodes precess in the opposite direction to that in which the Moon is orbiting Earth, one rotation every 18.6 years. Therefore, the Moon returns to the same node slightly earlier than it ...
