how long is kol nidre service

The Kol Nidre itself is a short prayer, generally taking about 20 minutes to chant, as it is repeated three times. However, the entire Kol Nidre service on Yom Kippur eve typically lasts much longer, usually around 1.5 to 2 hours, depending on the congregation, with some Conservative synagogues including sermons or fundraising appeals that can extend the duration to 2 to 2.5 hours or more. Some services may be shorter or longer depending on local customs and embellishments by cantors and choirs.
