Offset

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

11 hours

Atlantic Time (ADT) is behind Philippine Time (PHT).

ADT: UTC-3

PHT: UTC+8

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 Atlantic Time and Philippine Time don't overlap on the same weekday. Philippine Time is 11 hours ahead of Atlantic Time.

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

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