How to Convert SST to HST
Converting between Samoa Standard Time and Hawaii Standard Time means accounting for a 1 hour gap — here's how to do it in under 10 seconds with no sign-up.
Pick the date and time in Samoa Standard Time (UTC -11) that you want to convert. Hit "Now" to load the current SST time instantly, or use "+1h" to step forward and compare.
The equivalent Hawaii Standard Time (UTC -10) time appears immediately. Since HST is 1 hour ahead of SST, most daytime conversions stay on the same calendar day.

Why Choose Our SST to HST Converter
When someone in American Samoa suggests 9:00 AM SST, that's 10:00 AM HST. This converter shows the overlap so both sides agree on one slot — no back-and-forth.
Late-night SST times can land on a different date in HST because of the 1 hour offset. The converter labels "next day" or "previous day" next to the result so you never send a message a day early or miss a deadline.
Daylight Saving adjustments can widen or narrow the SST–HST gap by an hour. During transition weeks many people get it wrong. This converter pulls the current UTC offsets automatically, so the result is right even on the changeover day.
Product launches, sports matches, and webinars are often announced in SST. Convert the event time to HST so you know exactly when to tune in — with a 1 hour difference, a morning event in American Samoa falls during work hours in United States.
