Terms of use

The short version: use the tools freely, but don't rely on a web page for anything where a wrong time could cause harm.

Use of the site

onlineclock.app is free to use for personal, educational and business purposes. You may link to any page and embed the clock widget on your own site.

Accuracy

We work hard to keep times, time zones and daylight saving rules correct, and we check clocks against an internet time server. But a web page depends on your device, browser and connection. Browsers can pause background tabs, devices can sleep, and sound can be muted. Don't use these tools as your only alarm or timer for medication, safety, legal deadlines, transport or anything else where a missed or wrong time could cause harm. Time zone rules change, sometimes at short notice; for critical scheduling, confirm with an official source.

No warranty

The site is provided "as is", without warranties of any kind. To the extent the law allows, we are not liable for any loss arising from using it.

Content and data

Text and design are © onlineclock.app. City search data comes from GeoNames (CC BY 4.0) and time zone boundaries from timezone-boundary-builder (ODbL); see About for all sources.

Changes

We may update these terms; the current version is always on this page. Questions: [email protected].
