Countdown Timer
Live countdown to any date. Date difference calculator. Shareable via URL.
⏳ Live countdown — tick-tock seconds counter using setInterval. The target timestamp is kept in memory; nothing is stored on any server.
🔗 Shareable URL — the "Copy link" button encodes the Unix timestamp as a URL parameter (?target=…). Anyone who opens the link sees the same countdown.
📅 Date diff — calculates both a calendar breakdown (years / months / days) and absolute totals (days, weeks, hours, minutes). Handles month-length differences correctly.
🔒 Privacy — all calculations run in your browser. No data is sent anywhere.
