Answer 1

An equinox is close to 12 hours of day and 12 hours of night

Step-by-step explanation:

An equinox happens twice per year, around mid March and mid September, when the center of the Sun passes through our equator and shines directly on it. During this day, we have close to the same amount of day and night. March Equinox corresponds to the beginning of spring in the Northern Hemisphere and autumn in the south.
