Candlelight Ceremony
This can be held at any time. Perhaps on the loved one's birthday or on the anniversary of his/her death. Or on another significant day such as the day they might have graduated from high school. Or as part of a Christmas caroling drive by. Any opportunity to let the grievers know that their loved one is not forgotten and you are honoring their grief, which is significant on days such as birthdays, Christmas, Memorial Day, etc.,
