How to Convert HST to SST
Converting between Hawaii Standard Time and Samoa 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 Hawaii Standard Time (UTC -10) that you want to convert. Hit "Now" to load the current HST time instantly, or use "+1h" to step forward and compare.
The equivalent Samoa Standard Time (UTC -11) time appears immediately. Since SST is 1 hour behind of HST, most daytime conversions stay on the same calendar day.

Why Choose Our HST to SST Converter
When someone in United States suggests 10:00 AM HST, that's 9:00 AM SST. This converter shows the overlap so both sides agree on one slot — no back-and-forth.
Late-night HST times can land on a different date in SST 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 HST–SST 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 HST. Convert the event time to SST so you know exactly when to tune in — with a 1 hour difference, a morning event in United States falls during work hours in American Samoa.
