An equinox occurs on the same day at the same time in both hemispheres?
Correct. The March equinox, which is typically March 21 but can vary by a day either way, is the spring equinox in the northern hemisphere, because the Sun us rising into the northern hemisphere. At that very same moment, it is the autumnal equinox in the southern hemisphere, because as the Sun is moving INTO the northern hemisphere, it is moving away from the southern hemisphere. The September 21 equinox sees the Sun moving south of the equator, so the spring equinox in the south, while it is the autumnal equinox in the North.
What is vernal and autumnal equinox mean?
it will fall on the 22nd September 2012 in the Northern Hemisphere. During an equinox the length of day and night in both hemispheres is very much the same . 12 hours day and night. After this date in the northern hemisphere the days will become shorter with the advance of winter
What are spring and autumnal equinoxes?
An autumnal equinox is when the day is just as long as the night and the days are getting shorter. This happens in late September for northern hemisphere and in late March for southern hemisphere. It is different in the two hemispheres because of the Earth's revolution around the sun.

The Spring Equinox. This is the day that both both daytime and nighttime are functioning in the exact same span of time. (IE. Daytime = 12 hours, Nighttime = 12 hours = Spring Equinox.)

What day of December does the autumnal equinox begin?
The autumnal equinox is not in December. In the northern hemisphere it is in September. In the southern hemisphere it is in March. In December you have the winter solstice in the northern hemisphere and the southern hemisphere has the summer solstice. Equinoxes and Solstices happen on the 21st of their respective months, though occasionally then can be on the 20th or 22nd.
How many months go between when the northern hemisphere receives direct rays from the sun as opposed to the southern hemisphere?
There is no time between these. On the day before the autumnal equinox, the sun is directly overhead in the northern hemisphere (at a latitude just north of the equator). The following day, it is directly overhead in the southern hemisphere (just south of the equator). The sun goes from being overhead in the northern hemisphere to the southern hemisphere instantaneously, the change happening at the autumnal equinox.
An equinox occurs on the same day at the same time in both hemispheres?
Correct. The March equinox, which is typically March 21 but can vary by a day either way, is the spring equinox in the northern hemisphere, because the Sun us rising into the northern hemisphere.

The Summer Solstice is the 21st December. The day with the most daylight hours. The least daylight hours are ;- Northern Hemisphere ; 21st December. Southern Hemisphere ; 21st June The two dates when day light hour and night time are equal is;- Vernal (Spring) Equinox ; 21st Match Autumnal Equinox ; 21st September. These two dates apply equally across the Earth.
What is the distinction of a December 21 day?

If May 15 gains time each day, it means the days are longer than 24 hours. If May 15 loses time each day, it means the days are shorter than 24 hours. However, in reality, the length of a day remains constant at 24 hours due to Earth's consistent rotation.
