7 days (that took just one minute to answer)
I would expect that period of time to comprise 3/4 of a full cycleof phases, or about 22.15 days.
1/4 of the complete cycle of phases = 7.4 days(rounded)
A full Moon cycle is about 29 1/2 days, so the quarter cycle is a little more than a week.
About 7 days.
I believe that the anwser is last quarter.
