@Gianni Ceresa @Michal Zima and everyone thank you for the kind responses. So by business days I mean in the U.S and simply put for now I'd like to exclude Sat/Sun from the calculation. So if i have a date of 6/7/2022 and another date of 6/15/2022 the count of days should be 7 days because i'm excluding sat/sun. Keeping it…

The data source is unfortunately an excel spreadsheet which has dates that are spread out over many years.
