The moon rotates on its axis exactly once during a lunar month, which is approximately 29.5 days. This synchronous rotation is why the same side of the moon always faces the Earth. Consequently, the moon's rotation period matches its orbital period around the Earth.
During the 100 years of the 20th Century (1901 - 2000), there were 228 solar eclipses and 13 times lunar eclipses.
The moon orbits around the Earth approximately once every 27.3 days. This period is known as a synodic month or lunar month.
The moon undergoes phases throughout the lunar month, transitioning from new moon to full moon and back, which affects its visibility from Earth. During the new moon, it's not visible, while the full moon appears bright and fully illuminated. In between, the moon showcases varying amounts of its surface illuminated, creating the crescent and gibbous phases. This cyclical change is a result of the moon's position relative to the Earth and the Sun.
There are typically 12-13 full moons in a year, with one occurring approximately every 29.5 days. This phenomenon is known as a "lunar month."
It relates to the amount of times the Moon goes around Earth, during the time it takes Earth to go around the Sun. A Month very roughly corresponds to the time it takes for the Moon to go around the Earth, with the word month coming from Moon.
About 29 days.
A lunar calendar year typically has about 354 days. Over 19 lunar years, this totals approximately 6,726 days (19 x 354). If an extra month is added 7 times, that adds about 30 days (as a lunar month averages around 30 days), resulting in a total of approximately 6,756 days. Thus, there are about 6,756 days in 19 lunar calendar years with the extra month included.

A solar and lunar eclipse do not occur every month because the orbits of the Earth and the Moon are tilted relative to each other by about 5 degrees. Eclipses can only happen when the Sun, Earth, and Moon align closely, which occurs during specific times known as eclipse seasons, roughly every six months. During these periods, if the alignment is right, a solar eclipse (when the Moon covers the Sun) or a lunar eclipse (when the Earth casts a shadow on the Moon) can take place. Thus, while eclipses can happen multiple times a year, they do not occur every month.
During the 100 years of the 20th Century (1901 - 2000), there were 228 solar eclipses and 13 times lunar eclipses.
May = 31 days = 744 hoursThe minute hand rotates around the clock once per hour = 744 timesduring May, as well as during any other month with 31 days in it.
In the lunar calendar system, a regular year consists of 12 lunar months, totaling approximately 354 days. When an extra month is added seven times over 19 years, this results in a total of 19 x 12 + 7 = 235 lunar months. Converting this to days gives us 235 x 29.53 (average length of a lunar month) = approximately 6946.55 days.

If you look at the stars at the same clock-time every night, the whole picture will appear to rotate 1 degree per day, 30 degrees per month.

A lunar eclipse can occur multiple times a year, but the frequency can vary. On average, there are about two to four lunar eclipses each year. Lunar eclipses can be partial, total, or penumbral, with total eclipses being less common.
