About HourZone.io

HourZone.io provides fast, accurate, and free time and date tools. No ads, no tracking, no sign-ups. Every tool loads instantly and works right in your browser.

We built HourZone because finding simple time information online shouldn't require wading through ads, pop-ups, or slow-loading pages. Whether you need the current week number, want to convert time zones, or calculate the difference between two dates, the answer should be one click away.

All calculations run client-side using your browser's built-in APIs. Time zone conversions use the Intl.DateTimeFormat API with IANA timezone identifiers for guaranteed accuracy. No data is sent to any server.

HourZone.io is open source and committed to privacy. We don't use cookies, we don't collect personal data, and we don't track individual visitors. See our Privacy Policy for details.
