2028 time change dates for New Hampshire
At 2:00 AM the clocks jump straight to 3:00 AM in New Hampshire. That hour never happens, and everyone loses an hour of sleep.
At 2:00 AM the clocks return to 1:00 AM, so that hour is lived through twice and the night is an hour longer.
New Hampshire keeps EST in winter and shifts one hour forward for the summer.

Economic Impact of DST in New Hampshire
The economic effects of Daylight Saving Time in New Hampshire are real but modest, and studies disagree on their size. Retailers and hospitality businesses generally favour DST, arguing that lighter evenings encourage shopping, dining out and other after-work spending — the US retail lobby was one of the main forces behind the 2005 extension of the DST period.
The transitions themselves carry a cost. Research from Chmura Economics has put the one-off economic cost of the spring change in the United States at roughly $430 million a year, driven by lost productivity, workplace injuries and the health effects of a disrupted night's sleep.
Technology and Time Changes in 2028
Phones, computers and anything else that syncs with an internet time server handle the transition on their own. What still catches people out in New Hampshire is the long tail of devices that don't: car dashboards, ovens and microwaves, wall clocks, older thermostats, and cheap alarm clocks with a DST setting hard-coded to a schedule that has since changed.
For anyone running servers, the transitions are a recurring source of bugs — duplicated or missing local timestamps around the changeover, cron jobs that fire twice or not at all, and stale operating system timezone databases. Storing timestamps in UTC and keeping the tzdata package current avoids almost all of it.
Background
- Roughly 70 countries use some form of DST, but they are concentrated in Europe and North America. Most of Africa and Asia do not.
- Germany and Austria-Hungary were the first countries to adopt DST nationally, in April 1916, as a wartime fuel-saving measure.
- The Uniform Time Act of 1966 ended a chaotic period in which US cities set their own clock-change dates, and established a uniform national schedule.
Agricultural Considerations
The story that DST was introduced for farmers has it exactly backwards. Farmers in New Hampshire and elsewhere were among its most persistent opponents, and the American farm lobby successfully campaigned to have national DST repealed after the First World War.
The reason is straightforward: farm work follows the sun, not the clock. Moving the clock forward just means doing the same work an hour earlier by the clock, while deliveries, markets and hired labour all shift with it. Dairy farmers make the point most often, since cows keep to their own schedule and take several days to adjust to a changed milking time.
Tips for New Hampshire
Use the phrase 'Spring forward, fall back' to remember which direction to change your clocks.
Be extra cautious driving the Monday after the spring time change - accident rates increase.
Use the extra evening daylight in summer for outdoor activities and vitamin D.
Update your car clock, microwave, and other manual clocks that don't auto-update.
Frequently asked questions
When do the clocks change in New Hampshire in 2028?
Clocks go forward on Sunday, March 12, 2028 and back on Sunday, November 5, 2028.
Which way do the clocks go?
"Spring forward, fall back" is the usual mnemonic: forward one hour in spring, back one hour in autumn.
Do I have to change anything myself?
Phones, computers and anything that syncs over the internet update on their own. Car clocks, ovens, microwaves and older wall clocks generally do not.
Is Daylight Saving Time being scrapped?
It has been proposed in many places and adopted in few. The European Parliament voted in 2019 to end mandatory clock changes and the change has stalled; in the United States the Sunshine Protection Act has repeatedly passed the Senate without becoming law. Most of the world that changes its clocks is still changing them.
