This free tool shows Time Zones on Google Maps, plus the current time and UTC offset for any location worldwide.
This zoomable Time Zone map shows time zone boundary lines anywhere in the world. For U.S. locations, you can also overlay city limits, county lines and state boundaries on the map.
Quick Tips for using this Time Zones map tool
- There are four ways to get started using this Time Zones map tool
- In the “Search places” box above the map, type an address, city, etc. and choose the one you want from the auto-complete list
- Click the map to see the Time Zone and current time where you clicked (Monthly Contributors also get Dynamic Maps)
- To search using GPS coordinates use the “Find lat long” box in the top right above the map*
- Click the ◉ button in the upper right corner of the map to use your current location. Click the ◉ button again to automatically update your location every 1, 5 or 10 minutes (Monthly Contributors also get an option to update every several seconds, shown as ◉A for Active).**
- Optionally, show US city limits, county lines, and county labels by checking the boxes in the lower left corner of the map

* You can search using various formats of latitude longitude, including degrees, minutes and seconds; degrees and decimal minutes; or decimal degrees
** The “Locate” button will be more accurate on smartphones and other devices containing a GPS; desktop browsers typically show an approximate location
*** Coordinated Universal Time or Universal Time Coordinated (UTC) offset is the number of hours ahead or behind the current time in Greenwich, England, adjusted for Daylight Saving Time (DST) if in effect. It is the number of hours time difference from Greenwich. Prior to 1972, UTC was referred to as Greenwich Mean Time (GMT).

Find Time Zones by radius or by drawing a line or shape
- To find Time Zones within a radius or near a line or shape you draw:
- Click the “Selection Tools” button in the lower left corner of the map
- – RADIUS SELECT: To find Time Zones within a radius, specify the mileage in the “Select map features within x miles of the
shapes I draw” box, then use the Point “Add a marker” tool to draw the center point of the radius
– TOUCHING A LINE OR SHAPE: To find Time Zones that touch a line or a shape you draw, use the Line tool or Shape tool to draw the shape, double-clicking when finished
– WITHIN DISTANCE OF A LINE OR SHAPE: To find Time Zones that are within a distance of a line or a shape you draw, first specify the mileage in the “Select map features within x miles of the shapes I draw” box, then use the Line tool or Shape tool to draw the shape, double-clicking when finished
- The Time Zones will be highlighted and listed in a “Results from map” box below the map, where you can copy
the selected Time Zones for use in a spreadsheet or other document
– Optionally, keep drawing shapes to select more Time Zones
- When you are finished selecting Time Zones, click the “DONE Selecting” button in the lower left corner of the map
FAQs for Time Zones
As with many things, time zone and time zone boundaries are much more complex than meets the eye. This is due in large part to the fact that there is no central global body that determines timezones; rather, time zones can be set at many different political levels (e.g. country, state, county, city, tribal region). Read more here.
- The Search places box uses a standard Google Maps geocoding engine, therefore you can type street addresses, road names, points of interest, etc. to see what time zone that location is part of, as well as the current time there
- Many of the map layers from which this information is extracted are very large, so it may take several seconds for all of the map layers to finish drawing
- Because the map layers are large, boundaries will not be shown if you are zoomed out too far
- Note that typing an address will zoom in the map very close, whereas typing a city or county by itself will show you a map with a wider view
- Disclaimer: While the number of decimals in the latitude and longitude displayed for the map marker may imply a positional accuracy of within a few feet, note that Google Maps and the source data may not be that accurate. Accordingly, this tool should not be used for legal nor surveying purposes or anything beyond entertainment value.
