About PST
A fixed, year-round offset.
Peru Standard Time (PST) keeps things straightforward—Peru lives on UTC−5 year-round, no daylight saving shifts to track, no clocks to change. It’s the same clock whether you’re scheduling a meeting in Lima at noon in January or July: simple, reliable, and easy to coordinate across borders.
IANA zones · the technical identifiers
The zone that resolve to PST.
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 PST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Is Peru Standard Time the same all year?
- Yes—Peru has used UTC−5 continuously since 1994, with no daylight saving adjustments.
- Does Peru ever observe daylight saving time?
- No. Peru has not observed daylight saving time in recent decades and has no upcoming transitions planned.
- How does Peru Standard Time compare to U.S. Pacific Standard Time?
- They share the same UTC−5 offset but differ completely: U.S. Pacific Time shifts for daylight saving, while Peru stays fixed, so part of the year they match and part of the year they don’t.
- Why did Peru stop changing its clocks?
- Peru discontinued daylight saving time in the 1990s, settling on UTC−5 permanently, simplifying business, transport, and communication schedules.
- What city represents Peru Standard Time?
- Lima, the capital of Peru, is the representative city for PST (UTC−5).
- Which countries use Peru Standard Time?
- Peru Standard Time (UTC−5) is used exclusively by Peru.
- Is Peru Standard Time good for global scheduling?
- Because Peru doesn’t move its clocks, UTC−5 is stable and easy to compare with other regions, though some zones with daylight saving will shift relative to Peru during their summer periods.
