seven
That's 1/4 of a full cycle of 29.53 days, or 7.38 days.
When the moon has already past full moon stage, and is again at "half moon" stage, that is last quarter, about 21 days after new moon.

about 3 or 4 days
About 22; slightly under that, by a few hours.
I would expect that period of time to comprise 3/4 of a full cycleof phases, or about 22.15 days.
Last quarter moon comes after the full moon
The time from New Moon to Last Quarter is 22.15 days.
last quarter moon
first is the full moon then it is the last quarter then it is the new moon and the last one is the first quarter
Waning gibbous lasts from Full Moon to Third Quarter, so it lasts about 7 days.
