I Have a column of cells in excel of format hh:mm (The day is NOT included) like:


1:45 (Any Times before 12:00 noon are considered NEXT DAY)

one (or more of these) is after midnight.

The Average of these times is = 20:46

But Excel AVERAGE gives 15:58

I would like to calculate this average without adding extra columns or using VBA Just one formula at the end of the column. By the way, I also need to exclude any blank entries in the column for the calculations.

Thanks in Advance

  • You'll need an averageif, I think - what do you want to average? Noon to noon like 11:59am is the latest? – Raystafarian Jul 21 '15 at 17:10
  • correct Raystafarian ... Wouldn't AVERAGEIF just exclude entries less than 12:00? rather than adding 24 hours and including them? – Flashheart Jul 21 '15 at 17:19
  • Well since you want to skew the timeline, it will be trickier, I thought you wanted to exclude some. – Raystafarian Jul 21 '15 at 17:22

Confirm as an array formula with Ctrl+Shift+Enter

To exclude blank cells -

  • Seems to work. Is there a way to exclude blank entries in the column? Or is that asking too much of the formula? – Flashheart Jul 21 '15 at 17:37
  • @Flashheart I edited my answer to account for blanks. – Kyle Jul 21 '15 at 17:57
  • Works great ... thanks so much :) – Flashheart Jul 21 '15 at 18:01
