How the Countdown Calculation Works
A countdown timer computes the difference between the target date/time and the current moment, then breaks it down:
| Unit | Calculation |
|---|---|
| Days | Total seconds ÷ 86,400 (floor) |
| Hours | Remaining seconds ÷ 3,600 (floor) |
| Minutes | Remaining seconds ÷ 60 (floor) |
| Seconds | Remaining seconds mod 60 |
This updates every second in real time. The timer accounts for your local timezone automatically.
