Date validation-no future dates

[Kal_Lam]

Maybe this post discussed previously should help you solve your issue:

Making constraint with date entry (allowing only today's date)

Hi @williamouchi, Welcome to the community! You could do the same as outlined in the image below: In the survey tab of your xlsform: [Image 0.01] Reference xlsform: Date Inputs (Past, Current, Future).xlsx (16.9 KB) Please note: This best works with Collect apps (KoBoCollect android app or ODK Collect android app). It may not work as it should in Enketo (at the moment). Have a great day!
