New Hampshire's time zone
New Hampshire keeps Eastern Time statewide: EST (UTC−5) in winter and EDT (UTC−4) from mid-March to early November. The Seacoast, the Merrimack Valley, and the North Country share one clock with Boston and the rest of New England.
State lawmakers have debated joining the Atlantic Time Zone year-round — effectively permanent daylight time — several times, but each bill was written to take effect only if Massachusetts and Maine moved as well, and none has. For now Manchester changes its clocks on the same national dates as the rest of the Eastern zone.

Frequently asked questions
Is New Hampshire all in one time zone?
Yes — the Seacoast, the Merrimack Valley, and the North Country all keep Eastern Time: EST (UTC−5) in winter and EDT (UTC−4) from mid-March to early November.
How many hours ahead of California is New Hampshire?
Three, in every month of the year. An 8:00 PM game in Manchester starts at 5:00 PM on Los Angeles clocks. Convert any hour: EST to PST.
Does New Hampshire observe daylight saving time?
Yes. Bills to adopt year-round Atlantic Time have all been conditioned on Massachusetts and Maine moving too, so clocks still change on the dates shown on the DST page.
