As I mentioned in a previous question, there will be a Blue Moon in July of 1996. Two independent authorities confirm this including the 1996 Observers Handbook published by the Royal Astronomical Society of Canada, and in the reference book Astronomical tables of the Sun, Moon and Planets by Jean Meeus, published in 1995 by William Bell Inc, Richmond Virginia. In fact, the later reference gives the following list of Blue Moons:
July 30 1996 3:58 January 31 1999 16:07 March 31 1999 22:49 November 30 2001 20:50 July 31 2004 18:06 June 30 2007 13:49 December 31 2009 19:13 August 31 2012 13:59 July 31 2015 10:44 January 31 2018 13:27 March 31 2018 12:37 October 31 2020 14:50 August 31 2022 1:36 May 31 2026 8:46 December 31 2028 16:49 September 30 2031 18:59 July 31 2034 5:55 January 31 2037 14:05 October 31 2039 22:37 August 31 2042 2:03 May 30 2045 17:53 January 31 2048 0:15 September 30 2050 17:33The 1996 Blue Moon occurs on July 1 at 3:58 Universal Time, and July 30, 10:35 Universal Time. If you live in North America, however, the Blue Moon will happen on June 30 because of the 5+ hour time zone difference.
