Hanukkah, the 25th of Kislev.

Tonight, December 21, is also the 25th day of the Hebrew month of Kislev.  Hanukkah!  The Maccabees overthrew the Greeks and rededicated the temple in Jerusalem.  There was only enough oil for the lamps for one day and it would take another eight days to make enough oil to keep the eternal lamp lit.  The oil burned for eight days, thus the miracle of Hanukkah.
