What time is it in area code 428?
Area code 428 is in the Atlantic time zone: UTC−4 in winter and UTC−3 while daylight saving time is in effect. Clocks go forward on 8 March 2026 and back on 1 November 2026. When it is 9 am in 428, it is 8 am Eastern, 7 am Central, 6 am Mountain and 5 am Pacific – so the working day here starts while the west coast is still asleep. The code's largest rate centers are Saint John, St. Stephen and Miramichi. Other codes keeping the same time in New Brunswick: 506.
Clocks run in your browser from the IANA time zone database, so they stay right between page rebuilds.

Questions about 428 and time
What time is it in area code 428?
The clock above shows it live. 428 keeps Atlantic time, UTC−4 in winter and UTC−3 in summer.
Does area code 428 observe daylight saving time?
Yes. Clocks go forward on 8 March 2026 and back on 1 November 2026.
Is 428 the same time as New York?
No. New York is Eastern time; 428 is Atlantic (UTC−4 against UTC in winter), so work out the difference from the clock above rather than assuming.
Why does a 428 caller reach me at an odd hour?
Two common reasons. Either the clocks differ by more than you expected – the offset changes twice a year and not everywhere on the same date – or the caller ID is not really 428 at all. Spam callers fake a local-looking number, so the displayed code says nothing about where the call came from.
