⏳ Countdown

Pick a date and time and the counter runs live to the second from your own clock — no accounts, no notification spam. After the moment passes it keeps counting up, which turns the same tool into a birthday, anniversary or "how long has that PR been open" counter.

Why the countdown is honest about clocks

Everything is computed between your device's clock and your chosen local time — the same subtraction your phone's alarm does. If the device clock drifts (they do, until the next network sync), so does the counter; for second-exact events like a rocket burn, trust the mission clock, not a browser tab.
