HAPPY NEW YEAR (ROSH HASHANAH - Jewish New Year 5776)! The New Year begins tonight at sundown.
This concludes the Shmita (Sabbatical year), on which there is more here and links. For biblical and historical background on Rosh HaShanah, see here and links.
Also, the Coptic Orthodox Church celebrated its New Year on 11 September, year 1732 according to the Coptic Calendar. Happy slightly belated New Year to them as well.
