I can understand why you would want to know the timetable of your uncles passing... but unless he decided to show up next to me and tell me that information I can not help you. Did he pass from a heart attack? I think there might be a three connection( three hours, three days, three weeks?) I am sorry that I am not more help to you and your family... but please believe me when I tell you your uncle is fine and around you. I would invite you to ask the question of him yourself and remain totally open for the answer. It may show up in the next song you here, conversation you have or maybe in the next article or book you read. However it comes, I believe you will get your answer.
Take comfort in knowing that he is safe and still very much apart of your life.
Thank you and all the best to you and your family.
