Twice.
Sed says: TWICE. From the Northern Hemisphere perspective: Once on March 20/21 .... sun's rays moving northward, and again on Sept 20/21 with sun's rays moving southward.
The sun is vertically overhead at the Equator during the equinoxes, which occur around March 20-21 and September 22-23 each year. During these times, the sun's rays are directly perpendicular to the Equator, resulting in nearly equal day and night lengths across the globe.
During the equinox, the sun is directly over the equator. This occurs twice a year, around March 21 (the vernal equinox) and September 23 (the autumnal equinox). On these dates, day and night are approximately equal in length, as the sun's rays hit the equator at a perpendicular angle.
The Equator is an imaginary line (great circle) on the Earth's surface, which is equidistant from both the geographic poles and lies in a plane perpendicular to the Earth's axis of rotation. It divides the Earth into the Northern and Southern Hemispheres.An Equinox is either of the two times during a year when the sun crosses the celestial equator. At this time, the length of day and night are approximately equal as the Sun is exactly above the Equator.The vernal equinox occurs around March 21, when the Sun moves north across the celestial equator. The autumnal equinox falls around September 23, as the Sun crosses the celestial equator going south.
From October to March
On March 21, which coincides with the equinox, the sun is directly overhead at the equator. This leads to increased heating of the surface, causing warm air to rise. As this warm air ascends, it creates a zone of low pressure, while cooler air from the surrounding areas moves in to replace it, resulting in a generally upward movement of air at the equator. This pattern contributes to the development of the Intertropical Convergence Zone (ITCZ), where trade winds from the Northern and Southern Hemispheres meet.
it is on the 26th march at 8:30pm.
From September 21 until March 21, the shortest shadow points north from the equator. From March 21 until September 21, the shortest shadow points south from the equator.
At the equinox (either one of them) the Sun is directly above the equator, neither north nor south.
Yes.
An equinox is when the sun crosses the celestial equator, resulting in day and night being nearly equal lengths all over the world. There are two equinoxes each year: the vernal equinox in March and the autumnal equinox in September.
