Need calculation script for using Yesterday's Date in a Dynamic Stamp

[Maverick84]

Hello all, this is my first post here!

My team wants a dynamic stamp that shows yesterday's date from whatever date the stamp is placed. I have scoured this community and multiple websites for this script and have found nothing. Please know that I know next to nothing about Javascript.

What is the script I need to use to calculate today's date -1?

Can this script for today be edited to subtract one day?

event.value = (new Date()).toString();

AFDate_FormatEx("h:MM tt, mm/dd/yyyy");

Thank you very much for your help!

Replace the first line with this:

var d = new Date();
d.setDate(d.getDate()-1);
event.value = d.toString();

Using this with   AFDate_FormatEx("h:MM tt, mm/dd/yyyy");   gives me today's date. I've tried it several ways but it never returns yesterday's date. HOWEVER, using it with   event.value = util.printd("h:MM tt, mm/dd/yyyy",d);   as Thom_Parker says below does return yesterday's date correctly.

Thank you kindly for your help!

I would go further, don't use AFDate_FormatEx

Just set it directly:

event.value = util.printd("h:MM tt, mm/dd/yyyy",d);
