Hi, Don't know if there is a direct method for this but one solution is to use formula: (YEAR(End Month) - YEAR(Start Month)) * 12 + MONTH(End Month) - MONTH(Start Month) + 1 Include "+1" in the formula depending if you want to include end month in the figure. Use "-1" if you don't want to include start or end month in the figure. For example feb17-oct17 would be 9 with the formula above and feb17-dec18 would be 23. Hope this helps! Br, Jaakko
