Q. I will be traveling a lot during Chanuka for my business requirement, and have some important questions. What is the minimum time that the Chanuka candles have to stay on?
A. Nitey Gavriel (31: 2) maintains that the time needed is measured in “Shaot Zemanios” namely that it varies according to the latitude of the place one is in. He adds that in the U.S. it would be approximately 45 minutes.
Horav Shlomo Miller’s Shlit’a opinion is that a half an hour during the correct time for lighting is enough everywhere. Many Poskim agree.
