FAQ
- How is the D-day number calculated?
- It is the number of whole calendar days between today and your target date, in your local time zone. The target day itself is "D-Day".
- Can I share the result?
- Yes, the "Copy share link" button gives you a URL with the date baked in, so anyone who opens it sees the same count.
- Is anything stored or sent?
- No. Everything runs in your browser; the date is only kept in the page URL you choose to share.
