When converting from HST to EST, the key reference points to remember are: 9:00 AM HST equals 2:00 PM EST, 12:00 PM noon HST equals 5:00 PM EST, and 5:00 PM HST equals 10:00 PM EST. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across HST and EST
For professionals scheduling meetings between HST and EST, 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
HST does not observe Daylight Saving Time, maintaining UTC-10 year-round. EST observes DST, switching to EDT (UTC-4). 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.
