9am in New York City is 8pm in Jakarta

Jakarta is 11 hours ahead of New York City. Jakarta runs on Asia/Jakarta (UTC+7); New York City runs on America/New_York (UTC-4). The difference is measured right now; it can shift by one hour during daylight-saving-time transitions.

New York City observes daylight saving time — shifting between EST (UTC-5) and EDT (UTC-4) — while Jakarta stays on WIB (UTC+7) year-round. The difference is 12 hours in New York City’s winter and 11 hours in New York City’s summer. Transitions happen in late March and late October for most Northern-Hemisphere DST zones, and late September/early April for Southern-Hemisphere ones — check the current date against the city’s DST schedule before anchoring a meeting at the edge of those windows.

Standard 9-to-5 business hours in Jakarta and New York City do not overlap. Teams operating across this pair either stretch their schedules — an early-morning call from the westward city lands as an evening call in the eastward one — or rely fully on asynchronous tools. Scheduled windows at the edges (first thing for one side, last thing for the other) are the usual compromise, with one side absorbing the unsocial-hours cost this week and the other side next week.

When planning recurring meetings across Jakarta and New York City, pin them to one city’s local time rather than UTC or the other city’s clock. That way, the meeting time stays stable for the person anchoring the schedule, and the other side absorbs the one-hour drift during DST transitions. The alternative — a meeting pinned to the non-DST city — means the DST city sees the meeting time “move” twice a year, which is how recurring calendar invites end up at 7am on someone’s calendar in October.
