It sets only approximately at noon, the actual time can vary a couple of hours each way. But the third-quarter moon is 90 degrees ahead of the sun (i.e. to the right when viewed from the northern hemisphere) as measured along the ecliptic. Therefore it must set a few hours before the sun.
In the same way the first-quarter moon rises during the day and the full moon rises at sunset.
There is no phase of the Moon that does exactly that every time, but approximately it is first-quarter, which is a half moon with the bright side to the west.To rise at noon and set at midnight the Moon has to be around zero degrees declination (i.e. on the equator) and on the ecliptic 90 degrees behind the Sun. That happens around the summer solstice, June 21, or the winter solstice, December 21.
The third man to step on the moon was Charles Conrad on Apollo 12.
Donald J. Barry answered on November 30, 1999, A: If the moon is visible in the western sky after sunset, then it is near the sun in the sky (because the sun also sets in the west). In this configuration, the sunlight falls mainly on the back side of the moon as seen from the Earth, and we only see a crescent of light on the thin region visible from both the sun and the earth. If the moon is rising as the sun is setting, then the two objects are nearly opposite one another in the sky. So we view the moon from the same vantage as the sun would (it would be as if one person (the sun) were looking over another's shoulder (the earth) at a third person (the moon). Anywhere the sun shines on the moon, we see. So the moon looks full.
It is happening all the time. The lunar cycle is the 29-day cycle of new moon, first quarter moon, full moon, last quarter moon and new moon again, and repeat.
Charles "Pete" Conrad (USA) was the third person to set foot on the moon. He set foot on the lunar surface on November 19th, 1969.
At the time of the "First Quarter" and "Third Quarter" phases, the moon appears half-illuminated. These occasions are roughly 7 days and 21 days after New Moon respectively, and Full Moon occurs at the time exactly midway between them. Note: Both phases are easily visible in the daytime. First Quarter rises in the east around Noon, and Third Quarter sets in the west around Noon.
The lunar cycle begins at the New Moon when the moon has just passed the sun in its travel from west to east in the "pm" sky, and it sets just after sunset. After a week the moon is a quarter of its way around the Earth and so at sunset it is high in the sky. This is called the First Quarter. The first Quarter Moon follows the sun from east to west and sets at midnight. When the moon has done half of its monthly journey, it is on the side of the Earth opposite the Sun and the Moon is Full. It rises at sunset and can be seen in the sky all night, setting at dawn. In the Third Quarter Phase, the moon is three quarters of the way around and at sunset it is directly below us. It has apparently shifted from the sunset area (at New Moon) to overhead at sunset (First Quarter) to Eastern horizon at sunset (Full Moon), to below us at sunset (Third Quarter). At Third Quarter, the Moon rises at midnight and will be high in the sky at sunrise. It will set about mid-day.

Nominally midnight.
Dawn.
The obviously desired answer is "a half-circle", because you originally saw the 3rd quarter moon, and a week later the Moon would have been new. So after another week, you would see the first-quarter moon. However, if you go outside on a clear evening, you will not see the third-quarter Moon, because the third-quarter Moon does not rise until midnight. So if you saw the third quarter moon high in the sky, it would have been at about 3AM. I don't know about YOU, but I'm hardly ever up at 3AM, and if I am, I'm inside. And if you do not see the Moon at night, all that tells you is that you don't see the Moon. Depending on the time, it may not be up yet, or it may already have set.
Well, first of all, February 22, 2014 was a Saturday. At 12:16 PM Eastern time on that day, the moon reached Third Quarter. So on either Friday or Saturday, the left half was illuminated, the right half was dark (as seen by people in the northern Hemisphere), it didn't rise until around Midnight, and it set around Noon.

Every month. One month, give or take is when the moon goes through its full cycle. From new moon to [waxing crescent] to first quarter (week one) then to [waxing gibbous] to full moon (week two) then to [waning gibbous] to third quarter (week three) to [waning crescent] and finally by the end of the fourth week, new moon again.
