Placing a Large Cup with a Lot of Oil
Question
Answer
The measure in the Gemara is until the feet disappear from the market, and the poskim wrote that it is half an hour after lighting the candles. Therefore, the candles must have enough oil to burn for half an hour after the stars come out. Even those who light at sunset must put enough oil to burn until half an hour after the stars come out.
However, there are those who believe that in our time the measure of the feet disappearing from the market has changed, and it is necessary to light until the measure of our days, because until then the miracle is publicized. Therefore, some are meticulous to put oil in a measure of several hours until the feet disappear from the market in our time. This depends on each city according to its character; some say it is the time when the stores close, and some are meticulous until the time when there are actually no passersby on the street who see your Chanukah candles. [In Bnei Brak, the closing of the stores is around 22:00, and the cessation of traffic on the streets is around 23:00-24:00].
