IANA zones · the technical identifiers
The zone that resolve to BOT.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.

Frequently asked questions
Common questions about BOT, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Does Bolivia observe daylight saving time?
- No, Bolivia has not observed daylight saving time since 1932. The country remains on Bolivia Time (UTC-04:00) throughout the year.
- When was the last time Bolivia changed its time zone?
- The last recorded change to Bolivia’s standard time occurred in 1932, after which the country settled permanently at UTC-04:00.
- Is Bolivia Time used anywhere else besides La Paz?
- Yes. Bolivia Time covers the whole country, not just La Paz: Santa Cruz, Cochabamba, Sucre and every other Bolivian city use the same UTC-04:00 clock. Other countries share the UTC-04:00 offset under their own names.
- Are there multiple time zones in Bolivia?
- No, Bolivia operates under a single time zone—UTC-04:00—ensuring nationwide consistency in scheduling and communication.
- How does Bolivia’s lack of daylight saving affect international coordination?
- Bolivia's clock never changes, but the gap between Bolivia and places that observe daylight saving time, such as the United States, Europe and Chile, shifts by an hour when those places change their clocks.
- What is the official abbreviation for Bolivia Time?
- Bolivia Time is commonly abbreviated BOT. Time zone databases label it with the numeric offset -04 (UTC-04:00), with no seasonal variant.
- Why did Bolivia stop observing daylight saving time?
- Bolivia tried summer time only once, from October 1931 to March 1932. When it ended, the country settled on UTC-04:00 as standard time and has not changed its clocks since.
