History of March Equinox in Sierra Leone and How to Celebrate/ Observe It
In Sierra Leone, the March equinox occurs on March 20th. This is the first day of spring in the northern hemisphere and the first day of autumn in the southern hemisphere. The March equinox is also known as the vernal equinox or the spring equinox.
On the March equinox, the sun shines directly on the equator and the day and night are of equal length. In Sierra Leone, the sun rises in the east and sets in the west, just as it does every day. However, on the equinox, the sun rises due east and sets due west.
During the equinox, the sun is said to be “in the equinox.” This is because the sun’s path across the sky (known as the ecliptic) intersects the celestial equator at this time. The word “equinox” comes from the Latin words for “equal night.”
The March equinox marks the beginning of astronomical spring in the northern hemisphere and autumn in the southern hemisphere. In the northern hemisphere, the March equinox is the day when the sun crosses the celestial equator from south to north. This happens on or around March 20th each year.
In the southern hemisphere, the March equinox is the day when the sun crosses the celestial equator from north to south. This happens on or around September 23rd each year.
At the March equinox, the sun is directly overhead at noon at the equator. It is also directly overhead at midnight at the 180th meridian (the International Date Line).
