About Waltham Time Zone
Waltham uses the America/New_York IANA time zone, the same zone used across most of the US Northeast, including Massachusetts, New York, and much of the Eastern Seaboard. Its standard time is UTC-5, known as Eastern Standard Time (EST), and its daylight time is UTC-4, known as Eastern Daylight Time (EDT). Because Waltham is in eastern Massachusetts, its business day aligns closely with Boston, Cambridge, and New York financial and corporate schedules.
Waltham does observe daylight saving time. In the United States, DST begins on the second Sunday in March and ends on the first Sunday in November; clocks move forward by one hour in March and back by one hour in November. For 2025, DST starts on March 9, 2025, and ends on November 2, 2025, so during that period Waltham runs on UTC-4 instead of UTC-5.
Geographically, Waltham is in the Eastern Time Zone, one hour ahead of the Central Time Zone, two hours ahead of the Mountain Time Zone, and three hours ahead of the Pacific Time Zone. That means when it is 9:00 AM in Waltham, it is 8:00 AM in Chicago, 7:00 AM in Denver, and 6:00 AM in Los Angeles. This matters for cross-US scheduling, especially for software, higher education, healthcare, and financial services teams that operate between Boston-area offices and other US regions.
