I have a spread sheet that displays sets of data over three days. In A I have the date and times for each minute of day 1, and the aggregate numeric data for that day in column C. I have day 2 time in E and the respective data in G, and day 3 in I with the data in K.

I have a formula that updates each of those days to today minus 3, 2, and 1, respectively, so the data continues to update to reflect the past 3 days.

I am trying to build a formula that takes the average data of those three days at each point in time, and displays it at the current time of the day. So, for example, at 8:00 am today, I would like to be able to show the average of the data at 8:00 for the past three days.

Can anyone help?
