On May 13, 2010, the Moon was new.
At 12 Noon ET on May 14, 2010, the moon will be just hours past New Moon, and will be 0.7% illuminated. That's about as close to invisible as it gets.
The moon phase on May7th 1969 was waning gibbeous - it decreased to half (or last quarter depending on your frame of reference) on May 9.
At just about any phase, you can see half of the Moon's surface. Close to new moon, however, it may be hard to see the dark side.
A full cycle is about 29.5 days, so a quarter cycle will be 1/4 of this, on average (divide 29.5 by 4). This is just an average; since the Moon's orbit is not a perfect circle, it may vary a bit.
At just about any phase, you can see half of the Moon's surface. Close to new moon, however, it may be hard to see the dark side.
The moon looks the same as always but depending where you are in the world it may be in a different phase.
