The vernal equinox, what and when is it ?
I overheard this on the radio this morning. There was some discussion/argument about it being today or tomorrow.
But what I want to know is what the heck is it ? Pls explain in layman's term. I checked my star trek calendar, and nothing is mentioned of this vernal equinox, what or when it is. Although it mentioned, March 22 is the birthday Captain Kirk. |

The vernal equinox is specific to each planet. It therefore would have no place on an interstellar calendar.

The equinoxes are the days when night and day are the same length (happens twice each year.) They go along with the summer solstice (longest day/shortest night in Earth's Northern hemisphere) and the winter solstice (shortest day/longest night in Earth's Northern hemisphere.) Basically, an equinox occurs when a line drawn through a planet's rotational axis is at right angles to a line drawn between the center of the planet and the center of its star.
The solstices occur when the line between star (sun) and planet (earth) and the line through the planet's rotational axis lie in the same plane. In other words, when the planet's tilt is directly toward or away from the star. Hope that helps.

Ah ha... now I get it.
So the Vernal equinox this year falls on both days march 20 and March 21 at the same time. that's wierd. The site also said Vernal equinox means “equal night of spring". But it ain't spring in the southern hemisphere. |

Just depends on where in the world you live...
In the eastern hemishere it occurs on March 21st and in the western hemisphere on March 20th. In the southern hemisphere it's the Autumnal Equinox.
