General reference, not professional advice
Information on USATimeZones.com is provided for general informational and educational purposes. It does not constitute legal, regulatory, financial, scheduling, broadcast, or operational advice. Time-zone rules and daylight saving dates are set by U.S. federal law and may be amended; specific edge cases (such as tribal lands, disputed boundaries, or counties that observe different rules from their state) may require independent verification.
No guarantee of accuracy
We make a reasonable effort to keep content accurate and up to date. Even so, the site may contain typos, omissions, or content that has fallen out of date since it was last reviewed. The "Last reviewed" date on each page is your best signal of how recently a guide was checked. If you find an error, please let us know so we can correct it.
Verify before acting
Always verify time-sensitive details against an authoritative primary source before relying on them, particularly for:
- Court appearances, contractual deadlines, or other legal matters where the wrong time can have real consequences.
- Travel — flight, train, or border-crossing schedules use carrier or operator local time, not your interpretation of the zone.
- Broadcast and live-streaming schedules — the broadcaster's stated time is authoritative.
- Financial-market hours — exchanges publish their own session times, which may differ from a generic "Eastern Time" interpretation.
Tools and calculators
The live clocks, interactive map, and time converter on this site are convenience tools. They rely on the time-zone database in your browser and on your device's clock, which may be out of sync with a national time standard. For high-precision needs, consult a synchronized network time source.
Third-party content
Where the site links to or embeds third-party services — for example, mapping libraries or advertisements — the accuracy and availability of that content are the responsibility of the third party, not USATimeZones.com.
No endorsement
References to specific cities, states, products, or services on the site are for illustration only and do not imply endorsement.
Use at your own risk
Your use of the site is at your own risk. To the fullest extent permitted by law, USATimeZones.com and its operators are not responsible for any loss or damage arising from reliance on information presented here. See the Terms of Use for the formal limitation of liability.
