Corrected entry: At the last supper, the Passover menorah used has seven candles (six candles plus a "shamash," the center candle use to light the others) An actual menorah should have nine candles (eight for the eight nights of Passover, plus the shamash).

Correction: This entry is wrong. A menorah (any menorah) has seven branches. The candelabra with nine branches is properly called a Hanukkiah, and is used only for Hanukkah, not for Passover or any other time.
