Answer 1

I think Equinox...

The word 'equinox' is derived from the Latin words aequus (equal) and nox (night). It means equal day and night. However, in reality, the day is longer than the night at an equinox

This occurs twice each year, around 20 March and 23 September. In other words, it is the moment at which the center of the visible Sun is directly above the equator.

At the equinox, the sun crosses the celestial equator to enter the sky's Northern Hemisphere. ... We have an equinox twice a year – spring and fall – when the tilt of the Earth's axis and Earth's orbit around the sun combine in such a way that the axis is inclined neither away from nor toward the sun.

These two crossings are very important for the inhabitants of Earth, because they mark the change in the direction the sun's rays fall on Earth. Specifically, on Sunday, the sun will move from the Northern Hemisphere to the Southern Hemisphere.

Hope it helps you!!!
