April 5, 2018 is what is known as Tomb Sweeping Day Festival, Qing Ming Festival. On this day families from near and far visit the tombs of their ancestors. If you Google Qing Meng Festival, you may enjoy reading about the history of the festival, and how/why it is celebrated. It is a very touching and inspiring story.
Many temples and monasteries schedule a yearly Qing Ming Ceremony.
The THE FILIAL PIETY SUTRA may be recited within your daily prayer offerings, if you feel so inclined. Reciting this Sutra brings blessing to our departed ancestors, it also benefits oneself – generating positive karmic merit.
