March equinox

The march equinox is when the Earth's center is equally far away from the North Pole and the South Pole. It happens two times every year, in March and September. Picture a big circle around the Earth that's divided into four equal parts like a quartered pizza. The March equinox marks the moment when the Sun is directly above the equator, which is that imaginary line that goes around the Earth's middle like a belt. On that day, there are about the same amount of daylight and nighttime hours all around the world. It's like when you share a pizza and each person gets one slice, everyone gets an equal amount of time to see the sunshine and take a nap in the dark.
