Hanuka began at sundown tonight. It's an 8-day celebration starting on the 25th day of the first month of Winter on the Hebrew calendar, marking the Maccabean revolt in 166 BCE.
There are only two ways to properly spell the name of the holiday: חנוכה or חנכה (The one on the left being more common today according to Wikipedia)
If you use any other alphabet, it is entirely phonetic, resulting in many options, none of them being more 'correct' than the other. However, the YIVO Institute for Jewish Research did decide that 'Khanike' most closely approximates the pronunciation. Their spelling is one of the least used in America, though, even if it has the most academia behind it.
There are more videos in my post from 2009 at this time.
