Offset

The time difference between Philippine Time and Atlantic Time is 11 hours.

11 hours

Philippine Time (PHT) is ahead of Atlantic Time (ADT).

PHT: UTC+8

ADT: UTC-3

Atlantic Time is currently observing daylight saving time; Philippine Time is not.

When to schedule

Standard business hours (9 AM–5 PM, Mon–Fri) in Philippine Time and Atlantic Time don't overlap on the same weekday. Atlantic Time is 11 hours behind Philippine Time.

With some flexibility, there’s a workable window outside standard hours:

  • 6 PM–8 PM in Philippine Time (7 AM–9 AM in Atlantic Time) — suggest 7:00 PM Philippine Time (8:00 AM Atlantic Time).

This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.

This window may shift by an hour during daylight saving time.

Public holidays in 2026

National public holidays can affect availability — a counterpart is likely off work on their own holidays, so it's worth planning meetings and deadlines around them.
