As I've found out recently, there is a way to use elapsed days (instead of working days in MS Project). But I use german MS project and there you can't use the english words. You have to stick with german wording. But the german equivalent doesn't work out well. I've tried so far:
- ed
- edays
- Vergangene Tage
- Verstrichene Tage
- ver t
- etage
If you know a office.com reference for all english time shortcuts (including elapsed days), it might also help, because they translate most office.com websites in other languages. But so far the only reference I've found is https://support.office.com/de-de/article/Create-and-link-tasks-with-Project-2007-368ab1ee-d6de-4511-9948-888680b35d3d which is not available in german (-_-)
