AST to PHT conversion table

What are the best hours to schedule a call between AST and PHT?

No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. Atlantic and Philippine are 11 hours apart, which is too far for an overlap, so somebody has to take a call outside their own working day. The least painful options are below, ranked by how close both sides sit to the middle of the afternoon.

Does daylight saving change AST to PHT?

Atlantic Time is currently on ADT and changes next on Sunday, November 1, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC-3 to UTC-4.

Philippine Time does not move its clocks at all, so its UTC+8 offset holds every day of the year.

Because the two sides do not move together, the answer to this conversion changes during the year. For part of the year the gap is 11 hours and for the rest it is 12 hours. The table above is built for today, not for an average day.

Is AST ahead of or behind PHT?

AST is behind PHT by 11 hours: when it is 12:00 pm in Atlantic, it is 11:00 pm in Philippine. One wrinkle worth knowing: AST and ADT are two names for the same zone, not two zones. Atlantic Time reads AST in winter and ADT in summer. When somebody types "ast to pht" they nearly always mean the zone rather than the literal winter offset, so this page resolves AST to America/Halifax and PHT to Asia/Manila and applies whichever offset is genuinely in force on the day.

Atlantic Time covers Halifax, Moncton and the Canadian Maritimes. Philippine Time covers Manila, Cebu and Davao. The identifiers behind them are America/Halifax and Asia/Manila, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
