::: Observe when solar eclipse and lunar eclipse occurred, the position among the sun, the earth, and the moon.

When the moon (new moon) covers the sun, the complete solar eclipse occurs; when the moon (full moon) enters the shadow of the earth, the complete lunar eclipse occurs. If only parts of the moon covers the sun or enters the shadow of the sun, it is partial eclipse. The phases of the moon will change when its location changed.
