How to calculate epimediologic week

Hi, I’m creating a form for people to fill when they arrive at the country. I’m asked to display the epidemiologic week depending on the day of entry. Is this possible???

Hi @joserapereira,

Would you mind explaining your requirement is detail so that the community could have a look and see if it’s doable in KoBoToolbox.

Have a great day!
