The National Aeronautics and Space Administration ( NASA ) defines the occurrence of 4 consecutive total lunar eclipses as a Tetrad. In the years 2014 - 2015 a rare Tetrad sequence will occur on the Jewish Holidays of Passover and the Feast of Tabernacles. In addition to the Tetrad occurrence, 2 total solar eclipses will complement the 4 lunar eclipses on the Jewish New Year and the Feast of Trumpets.
