Funny thing realize after listening from my mother..

As most of you knew that, my grandma just pass away on Sunday which is goddess of mercy(Kuan Yin) so call birthday. All the members in the family said that, the goddess of mercy took my grandma to the other world and enjoy. And the most important thing is every 7th day, we need to pray her. And another funny thing occur here, when she was in this world, almost the whole family will gather in my 2nd aunt house, where she live with my grandma, to like gather and see each other. Now, every 7th day occur on every Saturday. Does all this means that, my grandma can predict all this and go peacefully with all this arrangement?????Or other reason???Thats what I have been wondering, and the whole family was wondering just now before all went back home. This occur when my grandfather (father side), 3 years ago. My grandfather pass away on the 3rd day of Chinese New Year. As he had some difficulty in eating and doing "business", family decided to send him to the old folks home, to let the professional there look after him. Most importantly is that, the whole family went to see him on the 1st day of Chinese New Year, and he went peacefully on the third day on Chinese New Year, and another funny thing occur here too. As usual every 7th day, we need to pray him, and that time the 7th day was a Sunday, all his grandson and family, do not need to work. I am still wondering, is this all the work of god, or just the nature????
