score:4
Sadhu, Nyom. What ever day, is a good day to show respect toward the ancestors, to give Alms to the Sangha to benefit them, to listen to the Dhamma by your self. Don't forget, if it had not been done in the past by your ancestors you would not ever had met the Dhamma.
Of what one should not miss when giving: Sila, virtue, what ever dedicating, is just the good given, if it does not harm others.
Invite many to take part on the merits and share them with all.
