About HST to CST Conversion

Converting time between HST and CST requires understanding their time zone offsets and any daylight saving time adjustments. HST (HST) operates at UTC-10, while CST (CST) is set to UTC-6. This means CST is 4 hours ahead HST. For example, when it's 5:17 PM HST on February 3, 2026, it's 9:17 PM CST in CST. America/Chicago observes daylight saving time, switching between CST (UTC-6) and CDT (UTC-5), while Pacific/Honolulu does not observe daylight saving time. Use this converter to quickly find the equivalent time in CST for any time in HST, whether you're scheduling meetings, planning travel, or coordinating with teams across different time zones.
