I am looking for a formula that can tell me the "days since activation"(number found in column "U") . Each number represents "times used on given day", if blank, that means it wasn't used that day. I want this formula to work even when there will be gaps of data, indicating non use (e.g. Row 4). I Highlighted Yellow the cells which represent the activation of device (first use). In this example I counted the amount of cells (days) through column R.

Since I have the dates listed on Row 1, a second formula that would be helpful is, to find the leftmost cell from defined range (activation date) then grab the corresponding date from row 1 and return number of days to "todays date" and disregard the date in column R.

Any assistance will be greatly appreciated.

Thanks
