Countdown Timer
Create a live countdown to any date, event, or deadline.

🎉 The countdown has ended
How It Works
The countdown subtracts the current timestamp from your target date every second. When the difference reaches zero, the timer stops and shows a "Time's Up" celebration.
Use the quick presets for common intervals, or set a specific date and time for events like birthdays, deadlines, or the New Year.
Formula
remaining = target − now
days = ⌊remaining / 86400⌋
hours = ⌊(remaining % 86400) / 3600⌋
min = ⌊(remaining % 3600) / 60⌋
