About 22; slightly under that, by a few hours.
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.
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.
7 days (that took just one minute to answer)
It takes approximately 7.4 days from a full moon to reach the third quarter phase.
The time between each principal moon phase is roughly a week. Specifically, from New Moon to First Quarter Moon is about 7 days, from First Quarter to Full Moon is another 7 days, from Full Moon to Last Quarter Moon is approximately 7 days, and from Last Quarter back to New Moon is around 7 days as well.
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.
