Current time in HST
HST is UTC-10, used across Hawaii. The clock below runs at that offset rather than at any one city's local time, because an abbreviation names an offset: when the region switches for the summer, the city moves and HST stays where it is.

Hawaii uses HST all year: there is no summer switch to track.

How it works
The offset comes from the IANA time zone database rather than a table we typed out, read through the Pacific/Honolulu entry, so it follows the same data your operating system uses and cannot drift out of date on its own.
Frequently asked questions
Does HST change with daylight saving?
No, and this region never switches at all. Hawaii stays on HST at UTC-10 through the whole year, so the arithmetic against your own clock only changes when your side moves.
Does HST mean only one thing?
Here, yes: these letters map to one offset, UTC-10, used by Hawaii. That is not true of every abbreviation, which is why the safe habit for scheduling is to write the offset or the IANA zone name alongside the letters.
How do I convert a meeting time into HST?
Use the timezone converter linked above: pick the source zone and read the result. Doing it in your head is where mistakes come from, because you have to remember both sides' switch dates as well as the offsets, and the two hemispheres do not switch on the same weekends.
