Moonstrual cycle.
A Saros cycle is an eclipse cycle of approximately 18 years, 11 days, and 8 hours, after which the Sun, Earth, and Moon return to nearly the same relative geometry in a three-body system, leading to similar solar or lunar eclipses. This cycle consists of a series of eclipses that occur at intervals of 6,585.3 days, allowing for the prediction of future eclipses based on past events. Each Saros cycle typically produces around 70 eclipses, including both solar and lunar types.
The time period between eclipses can vary. On average, it can range from a few weeks to a few months. This is because eclipses occur in cycles, such as the Saros cycle, which repeats approximately every 18 years and 11 days.
The Saros cycle is an eclipse cycle with a period of about 18 years 11 days 8 hours (approximately 6585â…“ days) that can be used to predict eclipses of the Sun and Moon. One cycle after an eclipse, the Sun, Earth, and Moon return to approximately the same relative geometry, and a nearly identical eclipse will occur west of the original location.
An eclipse itself doesn't "take years to make," but rather, the cycles of eclipses occur periodically. Solar and lunar eclipses happen in cycles known as the Saros cycle, which lasts about 18 years, 11 days, and 8 hours. This cycle allows for similar eclipses to occur again after this duration. However, the exact timing and occurrence of eclipses can vary widely within this and other cycles.
The 18-year and 11-day period after which the pattern of lunar and solar eclipses repeats is called the Metonic cycle. This cycle is based on the synchronization of the lunar months with the solar year, allowing for the prediction of eclipses within this timeframe. It was named after the ancient Greek astronomer Meton of Athens, who first described it around 432 BCE.
There are two hormones that are responsible for the regulation of the menstrual cycle. They are called estrogen and progesterone.
On earth there are 2 eclipses, Lunar and Solar eclipses

The hormone responsible for triggering ovulation in the menstrual cycle is called luteinizing hormone (LH).

In general, there are two lunar eclipses and two solar eclipses each year. On average, about half are total and half are partial, so you can expect, over a span of years, to see one total lunar eclipse every other year. There are sometimes cycles of eclipses. In 2014-2015, there will be four sequential total lunar eclipses, with no partial eclipses in between; this cycle is called a "tetrad" and it isn't all that unusual. There will be eight such tetrads in the 21st century; this will be the second tetrad of the century.
