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.

Blue Moon in 2009

In 2009 there was a December Blue Moon on Thursday, December 31 because the month had two full moons.

There are two definitions of blue moons. The most common, and the one you likely know, is when two full moons occur in the same month. The second full moon is typically called a blue 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.

Harvest Moon

The Harvest Moon was on Sunday, October 4. The October Full Moon was the tenth full moon of the year and was the full moon in Aries. The Full Harvest Moon was the first full moon after the Autumnal Equinox, making it the first full moon of Fall.

Depending on the year, the Full Harvest Moon may either be part of the Summer or Autumn season. In 2009 it was part of Fall.

2009 Equinoxes and Solstices

Below are the dates for the equinoxes and solstices from 2009. None of the equinoxes or solstices fell on the same day as one of the full moons.

All four seasons during 2009 had three full moons, so no seasonal blue moons occurred this year.

The 2009 dates of the equinoxes and solstices were:

  • Vernal Equinox (Spring): March 20, 2009 at 7:44 AM
  • Summer Solstice: June 21, 2009 at 1:45 AM
