* Solar Eclipses: These occur when the Moon passes between the Sun and Earth, blocking the Sun's light.

* Lunar Eclipses: These occur when the Earth passes between the Sun and the Moon, casting a shadow on the Moon.

Each type of eclipse has different frequencies and cycles.

Solar Eclipses:

* Total Solar Eclipses: These are relatively rare at any given location, occurring about once every 360 years. However, somewhere on Earth, there's a total solar eclipse about every 18 months.

* Partial Solar Eclipses: These are more common, happening several times a year.

Lunar Eclipses:

* Total Lunar Eclipses: These occur a couple of times per year, on average.

* Partial Lunar Eclipses: These are also relatively frequent, happening a few times per year.

To give you a more precise answer, please specify:

* Which type of eclipse? (Solar or Lunar)

* What kind of eclipse? (Total, partial, annular, etc.)

* For which location? (Eclipses are visible in different parts of the world)

Once you provide this information, I can tell you how many years until the next eclipse of that type in that location.
