Convert a specific time from HST to CST
Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.
What is the time difference between HST and CST?
Central Time is 5 hours ahead of Hawaii Standard Time. To go from HST to CST you add 5 hours. That gap is not fixed. Across 2026 the distance between these two zones takes 2 different values, from 4 hours to 5 hours, because Central moves its clocks and Hawaii does not. This page recomputes it rather than assuming.

What are the best hours to schedule a call between HST and CST?
3 hours of the standard 9:00 am to 5:00 pm working day line up in both zones, from 9:00 am HST to 12:00 pm HST. In Central that window reads 2:00 pm to 5:00 pm. Outside it, one side is either not yet at their desk or already gone.
| HST | CST | Working hours | Note |
|---|---|---|---|
| 9:00 am | 2:00 pm | both sides | mid morning in Hawaii, afternoon in Central |
| 10:00 am | 3:00 pm | both sides | mid morning in Hawaii, afternoon in Central |
| 11:00 am | 4:00 pm | both sides | mid morning in Hawaii, afternoon in Central |
Does daylight saving change HST to CST?
Hawaii Standard Time does not move its clocks at all, so its UTC-10 offset holds every day of the year.
Central Time is currently on CDT and changes next on Sunday, November 1, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC-5 to UTC-6.
Because the two sides do not move together, the answer to this conversion changes during the year. For part of the year the gap is 4 hours and for the rest it is 5 hours. The table above is built for today, not for an average day.
Is HST ahead of or behind CST?
HST is behind CST by 5 hours: when it is 12:00 pm in Hawaii, it is 5:00 pm in Central. One wrinkle worth knowing: CST and CDT are two names for the same zone, not two zones. Central Time reads CST in winter and CDT in summer. When somebody types "hst to cst" they nearly always mean the zone rather than the literal winter offset, so this page resolves HST to Pacific/Honolulu and CST to America/Chicago and applies whichever offset is genuinely in force on the day.
Hawaii Standard Time covers Hawaii, which has never moved its clocks. Central Time covers Chicago, Dallas, Houston and Winnipeg. The identifiers behind them are Pacific/Honolulu and America/Chicago, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
