Blue Moon Facts

Dates of upcoming Blue Moons (Stolen from Wikipedia)

Blue Moons between 2005 and 2015

The following Blue Moons occur between 2005 and 2015. These dates use UTC as the timezone, months will vary with different timezones.

Using the Farmer’s Almanac definition of blue moon (meaning the third full moon in a season of four full moons) blue moons occur:

• August 19, 2005
• May 19, 2008
• November 21, 2010
• August 21, 2013

If the “Calendar Blue Moon” (1946-1999) definition is taken (meaning the second full moon in any given month) then blue moons occur [1]:

• June 30, 2007
• December 31, 2009
• August 31, 2012
• July 31, 2015

Note that the year 2018 (as well as 2037, 1961, 1942, 1999 etc.) will have a black moon (no full moon in the short month of February) – and this results in 2 blue moons in January and March.
