Anyone kind who can help me;

1) make the formulas become correct - show correct week numbers?

2). Explain how the formulas work - their components, maybe then I can work it out myself.....

For example, what does the numbers between [Finish], [Start], etc, mean?


"Week " & CStr(1+datediff("w";"1/1/20" & mid(Year([Finish]);3;2);[Finish]))

"Week " & CStr(1+datediff("w";"1/1/20" & mid(Year([Start]);3);[Start]))

"Week " & CStr(1+datediff("w";"1/1/20" & mid(Year([Deadline]);3);[Deadline]))

Also taking into concideration that weeks start counting from first 4-day week.

Thank you kindly
