Hi,
I have the following table":

Now iI created a column to have the weeknumbers

but when i look, the numbers are matching but the numbers of the week are off. as you can see these two records are created in week 45, and not 46.
What am i missing here?

Solved! Go to Solution.
WEEKNUM has an optional return type which establishes when the week begins (day of week and week of year):
WEEKNUM ( <Date> [, <ReturnType>] )
