I would like to know if after the Ne'ila (concluding) service of Yom Kippur, do we do a full Havdalah or just light a candle?
Dear Chava Miriam,
After Yom Kippur, we recite the Havdalah service over a cup of wine, and we say the blessing over a havdalah candle as well. Unlike Shabbat, this candle should be lit from a flame that was alight throughout Yom Kippur. We omit the spices, unless Yom Kippur occurs on Shabbat.
