TODAY IS THE FIRST DAY OF SPRING? (Vernal Equinox)


Recommended Posts

Umm...

It's Spring?

Where's the sun?

Where's the SPRING TIMER air?

Where are the hotties running around half naked?

somehow I'm not convinced!

Perhaps this article I dug up from AOL

can clarify this for me.

The Rite of Spring

Vernal equinox occurs on March 20

March 20 is a date that most of us recognize as symbolic of changing seasons. As we welcome spring, people south of the equator are actually gearing up for the cooler temperatures of autumn.

What Happens at the Equinox?

Far from being an arbitrary indicator of the changing seasons, March 20 (March 21 in some years) is significant for astronomical reasons. In 2002, at precisely 2:16 p.m. EST (19:16 Universal Time), the Sun will cross directly over the Earth's equator. This moment is known as the vernal equinox in the Northern Hemisphere. For the Southern Hemisphere, this is the moment of the autumnal equinox.

Equinox Means "Equal Night"

Translated literally, equinox means "equal night." Because the sun is positioned above the equator, day and night are about equal in length all over the world during the equinoxes. A second equinox occurs each year on September 22 or 23; in 2002, it will be on September 23 at 12:55 a.m. EDT (04:55 UT). This date will mark the autumnal equinox in the Northern Hemisphere and the vernal equinox in the Southern (vernal denotes "spring").RELATED LINKS

Reasons for the Seasons

These brief but monumental moments owe their significance to the 23.4 degree tilt of the Earth's axis. Because of the tilt, we receive the Sun's rays most directly in the summer. In the winter, when we are tilted away from the Sun, the rays pass through the atmosphere at a greater slant, bringing lower temperatures. If the Earth rotated on an axis perpendicular to the plane of the Earth's orbit around the Sun, there would be no variation in day lengths or temperatures throughout the year, and we would not have seasons.

Rituals and Traditions:

Modern astronomy aside, people have recognized the vernal equinox for thousands of years. There is no shortage of rituals and traditions surrounding the coming of spring. Many early peoples celebrated for the basic reason that their food supplies would soon be restored. The date is significant in Christianity because Easter always falls on the first Sunday after the first full moon after the vernal equinox. It is also probably no coincidence that early Egyptians built the Great Sphinx so that it points directly toward the rising Sun on the day of the vernal equinox.
