How do you make a QR code for a wedding invitation with a countdown?

Short answer

Create a simple webpage with a live countdown timer to your wedding date, then generate a QR code for that page. Print the code on your invitation or a save-the-date card, and guests scan to see the days left.

You can build a countdown page using a free website builder or a simple tool that lets you embed a timer. Some wedding website services include a countdown feature as part of their template, which is the easiest route. If you already have a wedding website, add a countdown widget to the homepage and use that link for your QR code. If not, create a single page with the date, time and venue, plus a countdown clock. Then use a free QR code generator to turn that link into a code. Print it on your save-the-date card or invitation, with a line like "Scan to see the countdown". Test the code on your own phone and a friend's phone before printing. Remember that the countdown only works if guests have internet access, so it is a nice extra rather than a replacement for the written date. You can also update the page later with travel details or a schedule, so the same QR code becomes useful as the day approaches. Keep the design simple and make sure the code is large enough to scan easily, at least 2cm square.
