Ideas for countdowns
| Event | Why count down |
|---|---|
| New Year | Celebrate the exact moment |

How it works
The timer subtracts the current time from your target every second:
remaining = target − now
days = floor(remaining ÷ 86,400 s)
hours = floor(remainder ÷ 3,600 s)
minutes = floor(remainder ÷ 60 s)
seconds = remainder
Tips
- Pick an exact time: events often start in the evening, not at midnight.
- Keep it open on a second screen or a TV during live events.
- Use the Date Difference Calculator for a quick "days until" number without a live display.
