Daylight saving time and the EST–HST gap

Eastern Time (EST/EDT) — US daylight saving time runs from the second Sunday in March to the first Sunday in November (clocks forward at 2:00 AM). UTC offset in January: UTC−5; in July: UTC−4.

Hawaii Time (HST) — HST does not observe daylight saving time, so its UTC offset is the same all year. UTC offset in January: UTC−10; in July: UTC−10.

Because the two zones switch on different dates (or only one of them switches), the gap changes twice a year. The converter above uses the exact switch dates for the date you enter, so it is always right — including the odd weeks in March/April and October/November.
