Happy Hanukkah! If you don't know, it is an important holiday for Jewish occurring around the same time as Christmas during the holiday season. Hanukkah is observed for eight nights and days, starting on the 25th day of Kislev according to the Hebrew calendar, which may occur at any time from late November to late December in the Gregorian calendar. One of the main elements of this holiday is the dreidel, also known as dreidle, a four-sided spinning top, played during the Jewish holiday of Hanukkah. Each side of the dreidel bears a letter of the Hebrew alphabet: nun, gimel, hei, and shin.
