If the moon is half full on November 2, on approximately what date will it next become full?

The complete cycle of lunar phases has a period of 29.531 days.

You've described two phases that are separated by 1/4 of the

complete cycle.

If the moon is exactly at First Quarter (half-full and getting bigger)

at, let's say, 12:00 Noon on November 2 where you are, then it will

be Full after

29.531 days / 4 = 7 days 9 hours 11 minutes.

That's 9:11 PM on November 9.
