About Gaithersburg Time Zone
Gaithersburg uses the America/New_York IANA time zone, the same zone used across much of the U.S. East Coast, including cities such as New York, Washington, D.C., Boston, and Miami. Its standard time is UTC−5, known as Eastern Standard Time (EST), and during daylight saving time it changes to UTC−4, known as Eastern Daylight Time (EDT).
Gaithersburg is located in Maryland, in the Washington metropolitan region, so its timekeeping closely aligns with federal offices, East Coast financial markets, Amtrak and airline schedules, and many technology, healthcare, and government contractors operating around the D.C. corridor. Because it shares the Eastern Time Zone with nearby major business centers, there is no time difference between Gaithersburg and cities like New York, Philadelphia, Atlanta, or Washington, D.C.
Daylight saving time in Gaithersburg follows current U.S. rules: clocks move forward on the second Sunday in March and move back on the first Sunday in November. For 2026, DST begins on March 8, 2026, when clocks advance from 2:00 AM to 3:00 AM, and ends on November 1, 2026, when clocks return from 2:00 AM to 1:00 AM; this matters when arranging international calls because Gaithersburg’s difference from London, Sydney, or Dubai shifts seasonally.
