Today's Date Widget?

Today's Date Widget?

I love the new in-line e-mail feature, but before I'm ready to start using it for my company, I'm hoping to solve one thing: When I send the PDF version of my weekly dashboard, I've embedded a little iframe in the title that simply pulls in "today's date." So, today's dashboard will say "Dashboard for the week of September 18th, 2015" where the date is pulled in via and styled with HTML.  Is there a way to achieve this with a widget or other method?  The iframe doesn't survive the e-mailing process.
