day (September 2), 9:30 a.m. on Monday, 10:30 a.m. Tuesday and 11:30 a.m. Wednesday. If you consider those times as approximate, they will hold true for much of the world.
• Moon's rising and setting time in your sky
• By the way, the moon is up during the day half the time. It has to be, since it orbits around the whole Earth once a month. Sometimes the daytime moon is hard to see because it's so near the sun in the sky. And consider that if the sun is low in the sky, a slim crescent daytime moon might be straight overhead, so that you'd have to crane your neck, looking up, to notice it.
• September 2012 guide to the five visible planets
• Ordinarily, we don't look up during the day to see such a thin crescent moon. That's one reason people are sometimes surprised to learn the moon is out so often during the day.
• But as the moon gets farther from the sun in our sky, the portion of its lighted half turned in our direction increases. In other words, the farther the moon is from the sun, the larger the visible phase of the moon … and the easier to see a daytime moon.
• Bottom line: In the first week of September 2012, look for the daytime moon in the west after sunrise!
• Understanding moon phases
• Why isn't there an eclipse every full moon?
• Does the dark side of the moon really exist?
