Hanukkah spans eight nights and days of remembrance and ritual. The U.S. Postal Service joins the celebration with a new Hanukkah stamp in 2016. The stamp art depicts a menorah in the window of a home, viewed as if from inside a room. The white window trim is visible through the branches of the menorah, which echo the tangle of snow-covered tree branches beyond the glass. In 2016, Hanukkah begins at sundown on December 24. Art director Ethel Kessler designed the stamp with original art by William Low.
