Hi there. I am yusazhao, the independent developer behind timezone-map.com. I own, build, and maintain TimezoneMap from Hangzhou, China. It is a small, hands-on project—not a large media company or a scraped directory of other people’s pages. I write and edit the explanatory pages and guides, and I am responsible for keeping the tools and time-zone notes accurate against IANA/TZDB rules as the server timezone data updates.
Like many people who work online, I deal with cross-border scheduling: friends in other zones, clients on other continents, and flights that cross several U.S. offsets in one day. Manually tracking Daylight Saving Time (DST) changes and multi-zone countries is easy to get wrong. I wanted a fast, readable place to check times without heavy clutter—so I built this site and keep improving it.
Who this site is for
TimezoneMap is for people who need a clear answer right now: remote teams picking a meeting hour, travelers reading ticket times, and anyone comparing clocks across the United States, Russia, Canada, Australia, Mexico, Brazil, New Zealand, or Chile. The tools are free to use. There is no account and no paywall.
What you find here
These are the main sections (same names as in the menu):
- Country time zone pages: Live clocks and zone notes for the United States, Russia, Canada, Australia, Mexico, Brazil, New Zealand, and Chile. Most include a static time zone map image; New Zealand focuses on live clocks and notes without a map image.
- World Meeting Planner: Set a base city, add remote cities, and see overlapping office hours for today on one timeline.
- Time Zone Converter: Convert a chosen date and hour across cities, plus pair pages (for example EST to PST) for common routes.
- Flight Time Calculator (U.S. Multi-Layover Reminder): Enter local ticket times for a multi-stop U.S. itinerary to see flight times, layover windows, and airport vs body clock at each stop.
- Calculate Days: Add days or weeks to a date, count days between dates (with optional weekend/holiday filters), and look up ISO week numbers.
- Timezone Guides: Original how-tos on meeting across zones, daylight saving quirks, country clocks, flights, and date math—see the guides library.
How the times are calculated
Live clocks and conversions use civil time rules from the IANA Time Zone Database (the same family of zone IDs you see in software, such as America/New_York or Australia/Sydney), as exposed through PHP’s timezone support on the server. When a page shows an abbreviation like EDT or PST, it reflects the offset for that zone on the date you are looking at—including whether daylight saving applies.
Country pages and guides also cite public references where it helps (for example overviews of national time rules). I write and edit the explanatory text on this site; it is not a bulk republishing of other websites.
Experience behind the tools
The product decisions come from real scheduling friction I have hit myself:
- Recurring meetings that break when only one country springs forward
- Arizona and other “no DST” exceptions that confuse calendar labels
- Multi-stop U.S. tickets where every airport prints a local clock
- Southern-hemisphere DST seasons that do not line up with U.S. or European weekends
That is why the Meeting Planner focuses on overlap for today, why pair pages emphasize a specific date, and why the flight tool separates airport local time from how long a layover feels.
Editorial standards and limits
I aim to keep pages fast, readable, and useful for everyday planning. Time zone and DST rules change. Airlines, governments, and calendar apps can disagree at the edges. Treat everything here as general reference, not legal, aviation, or medical advice. Before a high-stakes meeting, flight, or deadline, confirm with an official source (your airline, your calendar’s zone settings, or a government time authority).
When I find an error, I fix it. Guides and trust pages show an updated date when material changes. If something looks wrong, tell me—corrections help everyone.
