Official Proclaimation from the International Nazarene Beit Din.
Next Passover would occur before the Spring Equinox and therfore the additional month of Adar Sheni (Adar II) is added this year (traditionally identified as 5774) so that Passover will occur after the Spring Equinox.
The proclaimation is being made now (almost a year in advance) so that Nazarene congregations will know this year to use the 54 reading Torah reading schedule used for an extended year, and not the 50 reading schedule used in non-extended years.
