FAQs
What does “Use My TZ” do?
It applies your device/browser’s current IANA time zone (for example, America/New_York, America/Chicago or Europe/Oslo) to the Time Zone field. Detection follows your system/browser setting, not your VPN IP.
Why is America/New_York the default time zone?
It’s a neutral, widely understood default for first load. You can change it from the dropdown at any time or click Use My TZ to switch to your local zone instantly.
Will the alarm sound if the tab is in the background?
Usually on desktop, yes (provided you’ve interacted with the page so autoplay isn’t blocked and the site isn’t muted). On mobile, background tabs or a locked screen may prevent audio from playing.
Can I use my own alert sound?
Yes. Choose a preset, paste a direct HTTPS audio URL, or upload a local file. Use Test to preview and Stop to end the preview. The volume slider controls playback level.
How do I share my event timer?
Use Copy Shareable Link. The URL includes event name, date, time, time zone, and sound mode so others load the same configuration instantly.
How do I stop or change a running countdown?
Click Cancel Countdown to stop. Edit the event details or sound, then press ▶ Start Countdown again. (Pause/resume is not supported.)
How accurate is the countdown?
Timing uses the browser’s system clock plus your chosen IANA time zone (DST and offsets handled by the platform). If your device clock is incorrect, the countdown will reflect that.
Can I run multiple timers?
Yes—open each countdown in a separate tab or window. Each tab runs independently.
Does VPN affect my time zone?
No. Time zone detection uses your device/browser setting, not your IP. If it looks wrong, pick the intended zone from the list or click Use My TZ.
