The period of the complete cycle of phases of the moon is about 29 days. So, exactly 15 days after the moment of Full Moon, it will have just passed New Moon. If you can see it at all at that time, it will be the skinniest possible crescent, very close to the sun in the sky.
One week after the full moon, there will be a 3rd quarter noon. But you won't see it in the evening, since the 3rd quarter moon rises around midnight and sets around noon.
If tonight the phase of the moon is full when it rises what will be the phase 4 days from now is in the waning gibbous stage.
That is the first quarter moon which looks like a half moon.
No. There is a full moon every 29.53 days. This is the synodic period of the moon, based on the length of time it takes to go from on phase to the next repetition of the same phase.
The time from one full moon to the next ... or between two occurrences of any phase of the moon ...is 27.32 days.
an old phase or even a total eclipse

The "waning gibbous" phase lasts from 2 days after the full to 6 days after the full.

The moon in the days before and after a full moon appear as a gibbous moon. A gibbous moon is anything between a full moon and a half moon.

I learned this in science class- it takes 29 1/2 days for the moon to go from new moon to the next new moon.
