Constellations

This is a list of all 88 constellations split up into the months when they are best seen in the sky. The months listed assume that you are looking at the sky at 9:00 PM. For every hour later than 9:00, add half of a month. For every hour before 9:00, subtract half a month. The constellations are typically visible for more than just one month, depending on where you are on the Earth. If you need to know exactly when a constellation is visible, check in a star atlas or on a planisphere.
