Converting Eastern Standard Time to Hawaii Standard Time
Eastern Standard Time (EST) and Hawaii Standard Time (HST) are separated by a 5 hours time difference. HST is 5 hours behind EST. EST is UTC-5, used in United States, Canada, Jamaica, while HST is UTC-10, used in United States.
When converting from EST to HST, the key reference points to remember are: 9:00 AM EST equals 4:00 AM HST, 12:00 PM noon EST equals 7:00 AM HST, and 5:00 PM EST equals 12:00 PM HST. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across EST and HST
For professionals scheduling meetings between EST 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 5 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
EST observes Daylight Saving Time, switching to EDT (UTC-4) 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.
