HST to EST — Hawaii to Eastern Time

Eastern Time is 5 hours ahead of Hawaii in winter and 6 hours ahead in summer.

The conversion rule

From November to March, add 5 hours to Hawaii Time for Eastern Time: 12:00 PM HST is 5:00 PM EST. Hawaii never moves its clocks, so during EDT (March–November) you add 6 — noon HST becomes 6:00 PM in New York.

There is barely a workday overlap: 9:00 AM–12:00 PM HST / 2:00–5:00 PM EST in winter, and just 9:00–11:00 AM HST / 3:00–5:00 PM EDT in summer. Honolulu mornings are the only option.
