The new moon is the opposite of the full moon — the Moon sits between Earth and the Sun and its lit side faces away from us, so it is invisible. New moons in 2021: Jan 13, Feb 11, Mar 13, Apr 12, May 11, Jun 10, Jul 10, Aug 8, Sep 7, Oct 6, Nov 4, Dec 4.
Each month’s full moon has a traditional name from North American and European folklore — January’s Wolf Moon, June’s Strawberry Moon, October’s Hunter’s Moon, and so on.
A Blue Moon is the second full moon in a single calendar month — it happens because the 29.53-day lunar cycle is slightly shorter than most months. 2021 has the usual 12 full moons.
A Supermoon is a full moon that occurs when the Moon is near its closest point to Earth (perigee), making it look slightly larger and brighter. The full moon dates above are calculated to the minute in Universal Time (UTC) using the standard Meeus algorithm.
