New Hampshire • Live Time-Zone Reference

New Hampshire Time Zone

New Hampshire uses Eastern Time (ET) statewide. Concord, Manchester, Nashua, Portsmouth, Dover, Keene, Lebanon, Berlin and all 10 New Hampshire counties share the same official civil time. The state uses EST at UTC−05:00 during standard time and EDT at UTC−04:00 during daylight saving time.

Quick answer: New Hampshire has one time zone and no internal time-zone boundary. Use America/New_York for date-aware software calculations. New Hampshire law currently provides for the spring and fall clock changes, so the state continues to alternate between EST and EDT in 2026.

Do New Hampshire Borders Change the Clock?

No under current rules. Maine, Vermont and Massachusetts all use Eastern Time, so ordinary crossings at New Hampshire's state borders do not require changing the clock. The adjacent part of Quebec is also in Eastern Time, keeping the international border aligned for normal civil time.

New Hampshire Standard Time vs Daylight Time

How New Hampshire Time Works

Six facts explain nearly every New Hampshire time-zone question, from statewide Eastern Time to county coverage, border travel and the state's own DST statute.

01 · Statewide

New Hampshire Has One Time Zone

The entire state uses Eastern Time. There is no Central, Mountain or Atlantic Time area inside New Hampshire.

02 · Counties

All 10 Counties Share One Clock

Belknap, Carroll, Cheshire, Coos, Grafton, Hillsborough, Merrimack, Rockingham, Strafford and Sullivan all use Eastern Time.

03 · Cities

Concord & Manchester Match

The capital and the state's largest city share the same EST/EDT schedule, as do Nashua, Portsmouth, Dover and Keene.

04 · Borders

No State-Line Clock Change

Maine, Vermont and Massachusetts also use Eastern Time, so New Hampshire's state borders do not create a time-zone shift.

05 · IANA

Use America/New_York

America/New_York is the correct date-aware IANA zone for current and future New Hampshire civil-time calculations.

06 · State Law

RSA 21:36 Codifies the Seasonal Change

New Hampshire law expressly provides for the March advance and November return between standard and daylight time.

Does All of New Hampshire Have the Same Time?

Yes. New Hampshire uses Eastern Time statewide. The state is divided into 10 counties—Belknap, Carroll, Cheshire, Coos, Grafton, Hillsborough, Merrimack, Rockingham, Strafford and Sullivan—and none contains a time-zone exception. The Seacoast, White Mountains, North Country, Merrimack Valley and Connecticut River communities all switch between EST and EDT together.

10 countiesEvery New Hampshire county follows the same official Eastern Time rules.
No in-state zone lineYou never change official time zones simply by traveling between New Hampshire communities.
One seasonal switchWhen New Hampshire moves between EST and EDT, the entire state changes together.

Is New Hampshire Ending Daylight Saving Time?

No change is in force as of August 20, 2026. Current RSA 21:36 defines Eastern Standard Time as New Hampshire's base standard and advances the state's clock one hour from the second Sunday in March until the first Sunday in November.

House Bill 1149 proposed removing the seasonal advance after Massachusetts, Vermont, Rhode Island and Maine enacted substantially similar permanent Eastern Standard Time laws. The New Hampshire House designated HB 1149 Inexpedient to Legislate on March 11, 2026. The proposal therefore did not change New Hampshire's current EST/EDT schedule.

Visual Geography

Sources & Methodology

CalendarHours uses location-aware, date-aware time-zone logic rather than permanently hardcoding New Hampshire as UTC−5 or UTC−4. America/New_York supplies the Eastern Time rules used throughout the state.

The IANA Time Zone Database is the primary rules source for civil offsets and transitions. The latest release verified for this page is tzdb 2026c, released July 8, 2026. New Hampshire's current statutory clock rule is checked against RSA 21:36, the 10-county structure against RSA 22:1, and the 2026 DST proposal against official General Court bill status and House records.
