Usr Formula Column to Assign Date Values

I calculate
Startdate (01.01.2022) plus number 5 (days) = 06.01.2022.
It works, but i need the result in a “date” format to filter or to use it with workload widget.

The DATEVALUE function converts a date that is stored as text to a serial number that Excel recognizes as a date. For example, the formula =DATEVALUE(“1/1/2008”) returns 39448, the serial number of the date 1/1/2008. Remember, though, that your computer’s system date setting may cause the results of a DATEVALUE function to vary from this example.
The DATEVALUE function is helpful in cases where a worksheet contains dates in a text format that you want to filter, sort, or format as dates, or use in date calculations.
