when do you light a yahrzeit candle on yom kippur
Yahrzeit candle The yahrzeit candle is lit during the week of Shiva (mourning). It is also lit at sundown on the eve of the yahrzeit (anniversary of the death) and at sundown preceding the start of Yom Kippur and at sundown preceding the last day of Succot, Passover and Shavuot. These holidays all have yizkor (memorial) in synagogue as well.
Christmas lights The Christmas tree was adopted in upper-class homes in 18th-century Germany, where it was occasionally decorated with candles, which at the time was a comparatively expensive light source. Candles for the tree were glued with melted wax to a tree branch or attached by pins. Around 1890, candleholders were first used for Christmas candles. Between 1902 and 1914, small lanterns and glass balls to hold the candles started to be used. Early electric Christmas lights were introduced with electrification, beginning in the 1880s.
