An equinox is the time of year when the earths equator lines up with the centre of the sun, that is it is not tilted with regard to the sun. This happens twice a year at a specific time, about March 20/21 and September 22/23. It is just a moment of time when it is exact but the day is incorrectly but generally referred to as the equinox.

How many times per year do you have days in which the number of hours day and night equal what are the names of those days?

In the northern hemisphere these days are called the Vernal Equinox (20-21 March) and the Autumnal Equinox (22-23 September). However, as these seasons are reversed in the southern hemisphere, current usage is the March Equinox and the September Equinox.

How many hours of daylight does Alaska have on the summer solstice?
It depends upon your latitude. The higher the latitude, the more daylight. Beyond the Arctic Circle there will be a period of time during the summer when the sun never sets, and the further you are north, the longer this period is. When I was in the arctic on holiday (!!) in 2006, the sun rose around the beginning of June and would not set until the end of July/beginning of August. I went to a concert at 11.30 at night, and did not get back to where I was syating until 1.30am the next morning - in blazing sunshine. It was a strange feeling! The downside is, of course, that for a similar period in winter, depending upon your latitude, the sun will never rise, and so you will be in a long period of darkness, or at least, twilight.

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.
What is the day whr nthe earth is not tilted toward the sun?
