Convert a specific time from WIB to ADT

Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.

What is the time difference between WIB and ADT?

Atlantic Time is 10 hours behind Western Indonesia Time. To go from WIB to ADT you subtract 10 hours. That gap is not fixed. Across 2026 the distance between these two zones takes 2 different values, from 10 hours to 11 hours, because Atlantic moves its clocks and Jakarta does not. This page recomputes it rather than assuming.

WIB to ADT conversion table

Every hour of Sunday, September 27, 2026 in Jakarta, with the matching reading in Atlantic. 10 of the 24 hours land on a different calendar date in Atlantic, which is the part people get wrong when they schedule across this pair.

What are the best hours to schedule a call between WIB and ADT?

No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. Jakarta and Atlantic are 10 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 WIB to ADT?

Western Indonesia Time does not move its clocks at all, so its UTC+7 offset holds every day of the year.

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.

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 10 hours and for the rest it is 11 hours. The table above is built for today, not for an average day.

Is WIB ahead of or behind ADT?

WIB is ahead of ADT by 10 hours: when it is 12:00 pm in Jakarta, it is 2:00 am in Atlantic. 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 "wib to ast" they nearly always mean the zone rather than the literal winter offset, so this page resolves WIB to Asia/Jakarta and AST to America/Halifax and applies whichever offset is genuinely in force on the day.

Western Indonesia Time covers Jakarta, Bandung and Medan, the most populous of the three Indonesian zones. Atlantic Time covers Halifax, Moncton and the Canadian Maritimes. The identifiers behind them are Asia/Jakarta and America/Halifax, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
