Special Day Counter — Pro Edition

Is an engineer-grade Chrome extension for tracking days to (countdown) or since (count up) the moments that matter—product launches, anniversaries, exams, migrations, you name it. Open the compact popup, add a title and a local date & time, and the extension calculates a precise, live-updating breakdown (days, hours, minutes, seconds). A clearly marked Primary event sits at the top with a bold timer, while your full list remains neatly organized below.

Designed for professionals, the interface emphasizes clarity and precision: tabular numerals for stable timing, explicit local-time formatting, and a visible time-zone indicator. You can Set/Unset Primary, Copy a clean summary (title • D-Day label • local date/time • formatted countdown), or Delete entries. If you only care about the date, leave the time at 00:00—everything still calculates correctly. All math runs locally and the UI updates every second, so it’s fast, private, and reliable even without internet.
