How long does a waning moon last?

Question

i heard our last full moon was on the 16th, so how long is the maning moon gonna last???

Answer 1

13 days, or so.  Yep, you're right, the last full moon was indeed on the 16th and if you don't count that day, then it'll be 13 days till the next new moon and from that point till the next full moon the moon will be waxing.  With the night of the 1st Quarter coming sometime in between just like when in the middle of the 13 day period (during it's waning period) between full and new moons the moon will subject itself to the last quarter, and so forth, and so on!  

Answer 2

Technically, a little over 14 days.  From the moment of new moon to the moment of full moon, the moon is waxing.  The rest of the time it is waning.

Answer 3

From full moon to bew moon - about 14 days.
