Show your readers how close Q-Day is. The countdown runs to 1 January 2029, the earliest credible expert estimate (Gartner), and updates every day. If the expert estimates move, the countdown moves with them. It is free and there is nothing to install.
Countdown widget
Pick a style, size, color and language. The preview and the code update as you choose; paste the two lines where the countdown should appear.

The card fits a sidebar or an article; the bar fits above or below a page header. More styles are coming, including a Q-Day meter with the qubit record and the next migration deadline.

What is Q-Day?
Q-Day is the day a quantum computer can break the public-key encryption (RSA and elliptic curves) that protects most of the internet. Read what Q-Day is and see the Q-Day timeline with every expert estimate.
