What are the differences between lunar and solar calendar?

The lunar calendar uses the phases of the moon to measure time, usually measuring the time from new moon to new moon as one month. The time required for the Earth to rotate around the Sun is one solar year. The solar calendar typically measures the time between vernal equinoxes.

Why is a lunar year 10 or 11 days shorter than a solar year?

Because there is an 11-day difference between a solar year and a lunar year, people using a lunar calendar insert an extra (13th) month into it every three years. In the solar calendar, people add a leap day to the month of February every four years.

How many solar days are there in a lunar calendar?

What are the similarities and differences between solar and lunar eclipses?

Solar eclipses result from the Moon blocking the Sun relative to the Earth; thus Earth, Moon and Sun all lie on a line. Lunar eclipses work the same way in a different order: Moon, Earth and Sun all on a line. In this case the Earth’s shadow hides the Moon from view.
