Converting Central Standard Time to Hawaii Standard Time
Central Standard Time (CST) and Hawaii Standard Time (HST) are separated by a 4 hours time difference. HST is 4 hours behind CST. CST is UTC-6, used in United States, Canada, Mexico, while HST is UTC-10, used in United States.
When converting from CST to HST, the key reference points to remember are: 9:00 AM CST equals 5:00 AM HST, 12:00 PM noon CST equals 8:00 AM HST, and 5:00 PM CST equals 1:00 PM HST. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across CST and HST
For professionals scheduling meetings between CST and HST, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 4 hours difference, the window of overlap may be limited. Use the highlighted working hours in the conversion table above to quickly identify suitable meeting times.
Daylight Saving Time Considerations
CST observes Daylight Saving Time, switching to CDT (UTC-5) during summer months. HST does not observe DST, staying at UTC-10 year-round. During DST transitions, the time difference between these zones may temporarily change by 1 hour. Always verify the current offset during spring and fall transition periods.
