Dates in New York time. The Moon as seen from the Northern Hemisphere.
How Moon phases work
The Moon has no light of its own: the bright part we see is the side facing the Sun. Over about 29.5 days it goes through the four main phases — New Moon, First Quarter, Full Moon and Last Quarter — with crescent and gibbous phases in between.
From the Southern Hemisphere the Moon looks upside down compared with the north: a waxing crescent is lit on the left instead of the right.
A supermoon is a Full Moon near perigee, less than 360,000 km from Earth, so it looks slightly bigger and brighter. A Blue Moon is the second Full Moon in a calendar month.
