Time Conversion Guide: Chile to HST

Chile runs on Chile Summer Time (CLST) at UTC-03:00, currently observing daylight saving time. HST runs on Hawaii Standard Time (HST) at UTC-10:00. That puts Chile 7 hours behind HST — a difference of -7h at the current offsets.

In practice, when it is 9:00 AM in Chile it is 2:00 AM in HST. Midnight in Chile is 5:00 PM in HST.Chile observes daylight saving time while HST does not, so the gap narrows or widens by an hour part of the year.

Why people convert Chile to HST time

Scheduling a call from Chile to HST: a 10:00 AM start in Chile lands at 3:00 AM in HST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Chile and HST are inside the 9-to-5 working day between 4:00 PM and 5:00 PM CLST time (9:00 AM–10:00 AM HST). That is roughly 1 hours of usable overlap.
Watching a live event or market open: Chile viewers need 2:00 AM in HST to catch a 9:00 AM start there, and 7:00 AM if the event is anchored to Chile.

Always state the zone abbreviation, not just the hour. "3:00 PM CLST" is unambiguous; "3 PM" across a -7h gap is not.
Block 4:00 PM–5:00 PM CLST as the recurring meeting window if you work primarily from Chile and need HST colleagues present.
Chile: Clocks fall back on Sun, Apr 4, 2027. Re-check this page after that date because the offset changes and so does the -7h gap.

About CLT (Chile Standard Time)

Chile Standard Time (CLT) is the standard time in Chile. During summer months (October to March), Chile switches to Chile Summer Time (CLST, UTC-03:00). Chile is the longest north-south country in the world.

About HST (Hawaii Standard Time)

Hawaii Standard Time (HST) is used in the state of Hawaii and does not observe daylight saving time. This makes HST one of the most consistent time zones in the US. The Hawaiian Islands are among the last places on Earth to see a new calendar day.

Best time to call between Chile and HST

Both Chile and HST sit inside the 9 AM – 5 PM working day between 4:00 PM–5:00 PM CLST, which is 9:00 AM–10:00 AM HST. That gives roughly 1 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

Chile and HST overlap for only 60 minutes (4:00 PM–5:00 PM CLST), so meetings have to be booked precisely.

Chile is 7 hours behind HST (CLST UTC-03:00 → HST UTC-10:00). The shared working window is 4:00 PM–5:00 PM CLST. Remember to re-check around daylight-saving transitions.
