Frequently asked questions
Quick answers about Terbit Clock, time zones, browser alarms and how the tools work.
Is Terbit Clock free to use?
Yes. The core Terbit Clock web tools are designed to be available without requiring an account.
Will an online alarm work if I close my browser?
Not reliably. Browser and device power-saving rules can suspend a web page. Keep the page open, the device powered and the volume audible when relying on a browser alarm.
Will a timer keep running if I refresh the page?
Terbit Clock stores active timer information in your browser so supported timer sessions can resume after a refresh. Browser or device restrictions can still interrupt alerts, so keep the page available when the finish alert matters.
How does Terbit calculate world time?
Terbit uses standard IANA time-zone identifiers and date-aware browser time-zone calculations, including applicable daylight-saving offsets.
Does Terbit Clock automatically handle daylight saving time?
For supported locations and dates, time-zone calculations use the applicable offset for that date. This is why city-based conversion is safer than manually adding a fixed UTC offset.
Can I use Terbit Clock on a phone?
Yes. Terbit Clock 2.0 is responsive and designed for phones, tablets and desktop browsers.
Do I need to create an account?
No account is required for the core clock, alarm, timer, stopwatch, converter and meeting-planning tools.
Why is Terbit Clock currently English only?
We are prioritizing a complete, high-quality English site before deliberately launching additional languages. This avoids publishing incomplete or duplicate language versions.
Does Terbit use affiliate links?
Some relevant pages may contain clearly disclosed affiliate links. These help support the service and are identified where appropriate.
