Remote Collaboration (AST and EST)
Schedule calls and sync projects between AST and EST.
Bộ đổi AST sang EST provides real-time conversion from Atlantic Standard Time (AST) to North American Eastern Time (EST/EDT). Compare the 1-hour or 0-hour difference, check live clocks, and coordinate schedules between Halifax, Puerto Rico, and New York. Understanding the Atlantic dynamic helps international shipping industries and tropical resort managers sync effectively with East Coast consumers and vendors.

Atlantic Standard Time (AST) is UTC-4. Parts of the Atlantic region (like Halifax) observe DST (ADT at UTC-3), while Caribbean territories (like Puerto Rico and Bermuda) stay on permanent UTC-4. Since Eastern Time changes between EST (UTC-5) and EDT (UTC-4), Puerto Rico is 1 hour ahead of Eastern in winter and shares the exact same time in summer. This zero-hour overlap in July or August surprises many visitors planning trips south from Miami.
Compare standard business hours and overlaps between AST and EST.

Select a date and time in the input fields above to convert between AST and EST with automatic daylight saving calculations.
Yes. If either region observes daylight saving time, the offset gap will adjust accordingly.
The standard reference zone for AST is America/Halifax and for EST is America/New_York.
Check the geographic location of your Atlantic zone contact to ensure correct 0-hour or 1-hour offset planning. While a maritime Canadian province observes summer adjustments normally, Caribbean nations prefer stable schedules year-round, merging perfectly with East Coast summers.
