Here the sun sets behind the next ridge. On Friday evening it is important to know the exact time of sunset, because the two Sabbath candles must be kindled at least 18 minutes before.
Shabbat is a day of rest from any work, and creating fire with a match is considered work.
Candle-lighting times for the various cities in Israel are published in the newspapers and announced on the radio. Notices are printed every week and are hung in public places like bus stops.
