About 22 days
In a typical 180-day school year, there are 45 days in a quarter. - 121lilacs
The New Moon, First Quarter, Full Moon, and Third Quarter are moments in time, with no duration. The Waxing and Waning Crescents, and the Waxing and Waning Gibbous phases, each last roughly a week.
The Moons Revolution around earth is about 30 days. So if you divide that by 8 (because there are 8 phases) you would get about 3.75 days in between each phase. That is New, Cresent, First Quarter, Gibbous, Full, Gibbous, Third Quarter, Cresent and then once it gets back to New Moon again, its starts over again.
The complete cycle of all moon phases is 29.53 days (rounded) on the average, with small variations depending on the exact interplay between the non-circular orbits of the earth and moon, which causes relatively small changes in their speeds along their respective paths. But those variations aren't really large enough for the casual observer to notice. For our practical purposes, it's accurate enough to say simply that the time period from any phase until the same thing shows up again is 29.53 days. (rounded)
Waning gibbous lasts from Full Moon to Third Quarter, so it lasts about 7 days.
A fortnight; fourteen days.
7.38 days (rounded)
a week.
the moon thats all just tell me my ans now
It would take 7 days
about 3 or 4 days
The waning crescent should begin roughly 14.7 days after First Quarter.
seven
I would expect that period of time to comprise 3/4 of a full cycleof phases, or about 22.15 days.
The time from New Moon to Last Quarter is 22.15 days.
1/4 of the complete cycle of phases = 7.4 days(rounded)
On the average, the moment of First Quarter comes 7.38 daysafter the moment of New Moon.
