Shabbat candles are lit by Jewish families to mark the beginning of Shabbat, the weekly day of rest. Traditionally, two candles are used, symbolizing the two commandments to remember and observe the Sabbath. The lighting usually occurs just before sunset on Friday evening. The act of lighting the candles is often accompanied by a blessing, expressing gratitude for the sanctity of the day. Once lit, the candles serve as a reminder of peace and tranquility, creating a warm atmosphere for family gatherings and meals throughout Shabbat.
