1/2 of 29.53 days = 14.77 days (rounded)
No. There is a full moon every 29.53 days. This is the synodic period of the moon, based on the length of time it takes to go from on phase to the next repetition of the same phase.
It takes 29.5 days for the moonto go through all the phases - from full moon to full moon. :)
The "waning gibbous" phase lasts from 2 days after the full to 6 days after the full.
If tonight the phase of the moon is full when it rises what will be the phase 4 days from now is in the waning gibbous stage.
Two weeks or, more precisely, about one half of the synodic period of 29.53 days.
Moon's phase cycle from New Moon through to Full Moon takes 29.53 days. More details are on the related link (Click 'Lunar phase' below)
I learned this in science class- it takes 29 1/2 days for the moon to go from new moon to the next new moon.
For the moon to get back to exactly the right phase, it takes a little longer than its sidereal orbit period, it takes 29 days, 12 hours and 44 minutes in total from full moon to the next full moon. This is known as the synodic period. It takes a little longer to go from phase to phase due to the earths progression around the sun in that time.
The phase is almost full, but not quite. The period of phases is about 29 days, so it takes 14.5 days for the Moon's phase to change from 'New' to 'Full'. If New Moon took place at some time on March 2, then Full Moon would occur on March 16, at about 12 hours later in that day.
29.531 days (rounded)
well thats one phase and all 8 phases takes 29.5 days so one would be approximately... 3.6875 days
That is the first quarter moon which looks like a half moon.
