1/4 of the complete cycle of phases = 7.4 days(rounded)
Approximately 14 days must elapse between the first-quarter moon and the third-quarter moon. This period represents half of a full lunar cycle, which lasts about 29.5 days.
seven
The time period between Full Moon and Third Quarter is usually 7 or 8 days, depending on the actual Full Moon and Third Quarter times.
The four main phases of the moon—new moon, first quarter, full moon, and last quarter—each occur approximately 7.4 days apart. The entire lunar cycle, lasting about 29.5 days, is divided into these phases: the new moon to the first quarter takes about 7.4 days, the first quarter to the full moon another 7.4 days, the full moon to the last quarter approximately 7.4 days, and the last quarter back to the new moon also about 7.4 days.
First of all , to correct your English spelling. It is 'phases' , NOT 'fases'. There are four phases. They are ;- New Moon (Waxing Crescent) First Quarter (Waxing Gibbous) Full Moon (Waning Gibbous) Last ( or third ) Quarter. (Waning Crescent) Next New Moon The bracketed terms are the visible shape of the Moon between each phase.
The first quarter and last quarter of the moon are each approximately 7 days apart from the new moon and full moon, respectively. Since the full moon occurs about 14 days after the new moon, the first quarter and last quarter phases are roughly 7 days apart from each other. Therefore, the first quarter and last quarter of the moon are about 14 days apart.
I would expect that period of time to comprise 3/4 of a full cycleof phases, or about 22.15 days.
About 7
The moon cycles through 4 phases every month. There are about 3 weeks between the first and last quarter phases of the moon.

About 22 days
From Last Quarter , through NEW Moon, to First Quarter is approximately 14 or 15 days.
