Rebecca, I light the Yahzeit candle on the 6th of every month to mark the date that Adam left us to live with the angels. Because I think that it is a symbol of respect & remembrance I light one even for the christian members of my family who are deceased. It is for Craig's Dad, Mom, Sister and Niece. I think that he likes that I do it (he doesn't say). I grew up with my Mom lighting them for her Dad, Mom & my brother (who died of childhood leukemia at the tender age of 7 in 1955) on their angel dates.
