Change first day of week from Sunday to Monday

[Devon van Dam]

Hi,

I am working with Excel 2016 and I can't find how to change the first day of a week (with the formula =WEEKNUM) from Sunday to Monday. It keeps showing me a different week for Sunday compared to the Monday - Saturday before.

Does anyone know how to change this for Excel 2016? Can only find it for older versions of Excel.

Thanks,
Devon

It hasn't changed. See Microsoft's documentation which explicitly applies to Excel 2016.
