Where are my goals stored?

Only in this browser's local storage on this device. Nothing is sent to a server, and your goals won't appear on other devices or browsers.

Can I add a date that's already passed?

Yes. If you add a past date, it will show how many days have passed, like D+3.

How is D-Day calculated?

It's calculated from midnight today to the target date, counting whole days rather than hours — so if your goal is tomorrow, it shows D-1 no matter what time of day you check.

D-Day Counter - Free Countdown to Any Date

What is a D-Day counter?

D-Day Counter is a tool that shows how many days remain until a date you choose, displayed as a large, easy-to-read number like D-5, D-DAY, or D+3. Whether you're tracking an exam, a trip, a wedding anniversary, or a project deadline, you can keep several dates in view at once, and every goal you add is saved in your browser so it's still there the next time you visit.

How to use it

Enter a goal name and date, then click "Add" — a new card appears in the list showing the D-Day count calculated from today. Add as many goals as you like, and remove any you no longer need with the "Delete" button. Everything is saved in this browser, so your goals will still be there the next time you come back.
