The Time Zone Map
Made by Rossilite, LLC
South America runs from UTC-5 in Colombia, Ecuador and Peru, through UTC-4 in Bolivia, Venezuela and western Brazil, to UTC-3 in Argentina, Uruguay and most of Brazil. Brazil alone spans four zones, including Fernando de Noronha at UTC-2. Chile and Paraguay still observe daylight saving on the southern calendar, so their clocks move in September and April, opposite to North America.
Zoom in on Brazil to see the internal zone borders between Amazonas, Para and Mato Grosso, or on the Chile and Argentina border along the Andes, where the difference is one hour for half the year.
How many time zones are there? 38 different UTC offsets are in use today, from UTC-12 to UTC+14, but the IANA database tracks hundreds of named zones because regions with the same offset often follow different daylight saving rules. This map draws a border only where the clocks actually differ right now.
Where does the border data come from? The open timezone-boundary-builder project, which combines OpenStreetMap boundaries with the IANA time zone database. The map is rebuilt with every release.
Is it free? Yes. No ads, no account, and it runs in any modern browser on desktop and mobile.
