// Set End Date to yyyy, mmm, dd for instance
var endDate = new Date(2017, 12, 13);
if(rightNow.getTime() > endDate)
app.alert(“This Document has Expired.”);

Open your pdf file.
The pdf file will get opened, voila, accompanied with a small window, saying:

One final word, you need to have Adobe Acrobat or the similar. Not the Acrobat Reader.
I am using Foxit PhantomPDF, Business Edition, Version
