Independent of daylight saving time, solar noon at the March equinox is about 11:57 in southwestern New Hampshire and 11:50 in southeastern New Hampshire. New England, which includes New Hampshire, is one of the few areas in the United States where solar noon is before noon. Because solar noon is earlier than most of the rest of the country, and New Hampshire is at a high latitude, sunset can be earlier than in most states.
