Death anniversary 祭祀
（重定向自Date of death）
A death anniversary is a custom observed in several Asian cultures including China, Georgia, Hong Kong, India, Iran, Israel, Japan, Bangladesh, Korea, Pakistan, Philippines, Russia, and Vietnam, as well as in other nations with significant overseas Chinese, Japanese, Jewish, Korean, and Vietnamese populations. Like a birthday, it is celebrated each year, but instead of on the date of birth of the individual being celebrated, it is celebrated on the day on which a family member or other significant individual died. There are also similar memorial services that are held at different intervals, such as every week.
