I'm trying to use the datetime_diff formula to configure a field similar to the ootb duration field in Smartsheet, but in Airtable.
I have a start-date and and end-date field. My goal is to have a duration field show the number of days between the start and the end dates.
Here are my constraints. 1) I want to be able to show only weekdays. 2) If the start date and the end date are the same I want the duration to equal 1, not 0.
Any suggestions?
