by December’s full Moon rises around sunset for several nights in a row: December 25, 26, and 27.
To our eyes, the Moon’s disk will appear fully illuminated a couple of days before a full Moon, so start looking on December 24 and 25 towards the east after sunset as it peaks over the horizon.
The winter solstice Moon takes the highest path along the sky and is above the horizon longer than any Moon—hence, it’s the longest night!
Conversely, near the summer solstice in June, the Sun is highest in the sky while the Moon has the lowest arc—hence, it’s the longest day!
