All dates and times are in United States Eastern Time for cities such as New York, adjusted for Daylight Savings Time for part of the year. The dates in your local time may shift.

The four primary lunar phases are the new moon, the first quarter, the full moon, and the last quarter. The lunar month last approximately a month or 29.53 days on average, also called a synodic month.

A new moon is the first lunar phase. The moon itself is not visible, though you may be able to “see” it because it blocks the visibility of the stars behind it. A full moon occurs when the Earth is directly between the Sun and the Moon, allowing the moon to appear illuminated entirely.

The first quarter moon occurs between the new moon and the full moon, and the last quarter moon occurs after the full moon and before the next new moon.

The second definition relates to having an extra full moon on the calendar during a season. When a season has four full moons, the third full moon of the season is also called a blue moon or a seasonal blue moon.
