Hi. Is there a formula that will countdown every 5 minutes, for example 4:59, 4:58 et. I can make a column listing five minute increments and reference those, but have not seen a more streamlined approach without using VBA. I am not sure how to apply VBA code into a certain cell, AQ7 for example. I need countdown for 15 minute and 30 minute as well. Thank you in advance for any direction.
