Last. No moon is called new moon.
It is difficult to tell exactly when the Moon is full just by looking; a Moon that's a day or two before the full moon is almost as bright as the full moon itself, and it remains quite bright for a day or two after.
When the moon has already past full moon stage, and is again at "half moon" stage, that is last quarter, about 21 days after new moon.
