Week Number from the today (metadata)

1. What is the issue? Please be detailed.
I want to extract the week number from the today in the metadata or is there something built in to know the week number directly from xlsform?

2. What steps can we take to reproduce this issue?

3. What have you tried to fix the issue?
I have tried the today type in metadata and extracting it using Excel formulas, but it is very complicated and I look forward to having it in the form itself.

4. Upload any forms or screenshots you can share publicly below.
