History of March Equinox in San Marino and How to Celebrate/ Observe It
The March equinox occurs every year on the 20th or 21st of March and marks the moment when the sun crosses the celestial equator from south to north. This happens at precisely 12:00 UT (Universal Time). In San Marino, the sun will rise in the east and set in the west, as it does every day, but the length of day and night will be almost exactly equal.
The March equinox is one of only two times in the year when the sun shines directly over the Equator and day and night are of equal length all over the world. The other time is the September equinox.
Equinoxes occur because the Earth’s axis of rotation is tilted at an angle of 23.5 degrees from the perpendicular to the plane of its orbit around the sun. This tilt means that, as the Earth orbits the sun, the northern and southern hemispheres take turns pointing towards and away from the sun.
Twice a year, at the March and September equinoxes, the Earth’s axis is pointing neither towards nor away from the sun, and so the sun shines directly over the Equator. At these times, day and night are of equal length all over the world.
The word “equinox” comes from the Latin for “equal night”.
