HST and PET on the World Map
The map below highlights the HST (Hawaii Standard Time) and PET (Peru Time) timezone regions across the globe.
HST – Hawaii Standard Time
UTC-10:00Hawaii Standard Time (HST) is the time zone for the Hawaiian Islands, 10 hours behind UTC.
- •Hawaii does not observe daylight saving time.
- •HST is 5 hours behind EST in winter and 6 hours behind EDT in summer.
- •Hawaii is one of only two US states that don't observe DST (the other is Arizona).
PET – Peru Time
UTC-05:00Peru Time (PET) is the standard time for Peru, 5 hours behind UTC.
- •Peru does not observe daylight saving time.
- •PET is the same offset as EST (UTC-05:00).

Understanding the +5h Gap: HST vs PET
HST runs on Hawaii Standard Time (HST) at UTC-10:00. PET runs on Peru Time (PET) at UTC-05:00. That puts HST 5 hours ahead of PET — a difference of +5h at the current offsets.
In practice, when it is 9:00 AM in HST it is 2:00 PM in PET. Midnight in HST is 5:00 AM in PET. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert HST to PET time
- Scheduling a call from HST to PET: a 10:00 AM start in HST lands at 3:00 PM in PET, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both HST and PET are inside the 9-to-5 working day between 9:00 AM and 12:00 PM HST time (2:00 PM–5:00 PM PET). That is roughly 3 hours of usable overlap.
- Watching a live event or market open: HST viewers need 2:00 PM in PET to catch a 9:00 AM start there, and 7:00 PM if the event is anchored to HST.
- Always state the zone abbreviation, not just the hour. "3:00 PM HST" is unambiguous; "3 PM" across a +5h gap is not.
- Block 9:00 AM–12:00 PM HST as the recurring meeting window if you work primarily from HST and need PET colleagues present.
