❓ Common questions
- Does the timer keep ticking if I leave the tab open?
- Yes, as long as the browser tab stays open and active. Background tabs may throttle timers, causing slight drift.
- Can I count down to a specific time of day?
- Yes. Use the datetime-local input to pick both a date and a time.
- What happens when the countdown reaches zero?
- The display switches to a 'Time's up!' message and then continues counting elapsed time past the deadline.
