How Time Is Calculated
The countdown calculates the exact difference between right now (updated every second) and your target date. Days = total remaining seconds ÷ 86,400. Hours = remaining seconds after removing full days ÷ 3,600. Minutes = remaining seconds after removing hours ÷ 60. Seconds = the final remainder.

The countdown target date is not saved between sessions. If you close the browser and reopen, you need to re-enter the date. The timer is calculated fresh from your target date each time.
The stopwatch uses JavaScript's performance.now() which is accurate to sub-millisecond precision. Display refresh is every 100ms so the displayed value rounds to 0.1 seconds.
