At the equinox day and night are of the same length all over the world because the Sun is in the plane of the Earth's equator, and that happens on March 21 and September 22 each year.
At other times the Sun is above or below the Equator, and day and night have unequal lengths.
The Vernal (Spring) one.
the vernal equinox is always on the 21 of march. that's the day I'm righting this. _______________________________ The equinoxes occur on March 21 and September 21, plus or minus one day because of the cycle of leap years. In the northern hemisphere, the vernal equinox is in March, and the autumnal equinox is in September; in the southern hemisphere, it's reversed. In 1978, the vernal equinox in the northern hemisphere was March 20, 1978 at 5: 10 PM GMT.
Equinox happens twice a year. The Vernal equinox is also called the Spring equinox in the Northern Hemisphere. The 2014 Vernal equinox was on March 20, 12:57 P.M. EDT.
This will happen in spring and autumn on days known as the equinoxes - roughly March 21 and September 22IN ADDITION:In the spring equinox on march 21 the earth tilts away from the sun. On September 23 the autumnal equinox, it tilts towards the sun. We are actually closer to the sun in the wintertime in the northern hemisphere.
It is called an equinox and it happens twice a year, once in March and once in September.
Don't understand your question. Equinox means "equal night", meaning the Northern Hemisphere and Southern Hemisphere both receive equal amounts of day and night. It signifies the beginning of Spring in the northern hemisphere and the beginning of Fall in the southern hemisphere.
March 20th is the spring or vernal equinox in the northern hemisphere
The vernal equinox is in March in the northern hemisphere and in September in the southern hemisphere.
Spring
Spring starts at the march equinox :)
When the Northern Hemisphere is in the time period of March 20-21, they are in the Spring Equinox. (Spring)
The "Vernal Equinox" is the beginning of "Spring" and the end of "Winter". The Autumnal Equinox is the beginning of "Autumn" or "Fall" and the end of "Summer". In the Northern Hemisphere, the Vernal Equinox is in March and the Autumnal Equinox in September each year.
In the northern hemisphere it is in September. In the southern hemisphere it is in March.

The Fall Equinox is the September Equinox in the Northern Hemisphere and the March Equinox in the Southern Hemisphere. The weather seasons can be roughly decided by the month in which the season starts and the two months following. northern hemisphere - September, October, November (begins Sept 22/23) Southern Hemisphere - March, April, May (begins March 20)
Equinox happens twice a year. The Vernal equinox is also called the Spring equinox in the Northern Hemisphere. The 2014 Vernal equinox was on March 20, 12:57 P.M. EDT.
the hemisphere that will experience there vernal equinox is the southern hemisphere because in the northern hemisphere will experience autumnal equinox and it is the opposite.
On March 20 for the Northern Hemisphere (this is the autumnal equinox in the Southern Hemisphere). The vernal equinox for the Southern Hemisphere will be either September 22 or 23.
