It is a popular misconception that the phenomenon of a total eclipse of the sun is a rare occurrence. Quite the contrary. Approximately once every 18 months (on average) a total solar eclipse is visible from some place on the Earth’s surface. That’s two totalities for every three years.

How often do eclipses repeat?

On average, it takes about 375 years for a total solar eclipse to happen again at the same location. By comparison, a total lunar eclipse, also known as a Blood Moon, can be seen from any location approximately every 2.5 years.

Is there an eclipse every 28 days?

Total solar eclipses happen when the moon crosses between the sun and Earth and casts its shadow onto our planet, but Earth doesn’t experience a total solar eclipse every month.
