There isn't a fixed number of lunar eclipses each year. Here's why:

* Lunar eclipses happen when the Earth passes between the Sun and the Moon, casting its shadow on the Moon.

* The orbits of the Earth and the Moon are not perfectly aligned. This means the Moon's path doesn't always line up perfectly with the Earth's shadow.

* The number of lunar eclipses per year can vary from zero to three.

There are typically two to three lunar eclipses each year because of the timing of the Moon's orbit. It's a fascinating celestial event!
