Description: Example calendar showing lunar phases. This sequence shows the moon each day from an assumed latitude of 45 north, and pictures taken approximately 25 minutes later every day. (The 25 minute shift was picked to duplicate observable periods, from a waxing crescent at sunset to full moon around midnight to a waning crescent at sunrise.)
