Formula to Generate Which week of the year it is based on date entered in ""Process Date"" Field.

I really appreciate your time and assistance. I started at a new company on a trial basis to help with data...not expected to have ever used QuickBase before but to see how quickly I can adapt and create what they need. My apps are pretty in depth so far...I had found a way to build form rules that produced the correct weeks but that would mean manually entering every week of the year into the form rules page...every year. I know that the answer is formulas, in excel this function would be easy but it is much more complicated in QuickBooks. I have watched several videos but I am expected to be able to show visual results weekly as well and I am only in 3 days a week. The other days I am at another job. Once I get the information going I want to do the full QuickBase University course directive and try to achieve certifications, assuming they hire me full time. But I have to get there first.
