Did anyone having the problem on extending their Survey123 form with JavaScript code? I was trying to get the day of week by passing the date I selected from the form to my JavaScript function and show the day of week on the form.

I found that the function returns 0 for Sunday when using Survey123 Connect while returns 0 for Monday when manipulating on every browser.

What I code in that function was simple, just return new Date(inputDate).getDay(); .

Hi Jack,

One thing to check is whether there is any difference in locale between your browser and Operating System?Different locales use different values for firstDayOfWeek.
