I am using the TEXT function like =TEXT(B1, "ddd") where B1 is formated as date to display the weekday. This works fine on an english regional system.
On a machine with a german regional setting the formula doesn't work because the format literal must be "ttt". So on a german system the formula would have to be =TEXT(B1, "ttt")
How can that same spreadsheet be used on a system with an English regional setting and on another machine with a German regional setting?
