Frequently Asked Questions
What is the time difference between PET and HST?
During standard time, Hawaii-Aleutian Standard Time is 5 hours behind Peru Time.
Does Peru observe Daylight Saving Time?
Peru does not observe Daylight Saving Time and has not done so since 1994. PET remains fixed at UTC-05:00 throughout the entire year, with no seasonal clock changes affecting business hours, market schedules, or international coordination.
How does Peru Time (PET) align with the US?
PET (UTC-05:00) is identical to US Eastern Standard Time (EST) during the Northern Hemisphere winter — Lima and New York run on the exact same clock. When the US shifts to Eastern Daylight Time (EDT, UTC-04:00) in summer, PET falls one hour behind, but a full shared workday between Peru and the US East Coast remains entirely achievable without scheduling concessions on either side.
Does Hawaii observe Daylight Saving Time?
Hawaii does not observe Daylight Saving Time and has not done so since 1947, remaining fixed at UTC-10:00 year-round. At roughly 20° North latitude, Hawaii's daylight hours vary by only about 1.5 hours between the summer and winter solstices — far too little to justify the disruption of a seasonal clock change.
Why is it called Hawaii-Aleutian time?
The name combines two geographically distant US territories that share the same UTC-10:00 standard offset: the Hawaiian Islands in the central Pacific and the westernmost Aleutian Islands of Alaska, which extend past the 180° meridian into the Eastern Hemisphere. Despite sharing a base offset, they behave differently — Hawaii observes no DST, while the Aleutian communities such as Adak do advance to HDT (UTC-9) each summer.
