WIB to EST
Jakarta is 12 hours ahead of New York in winter and 11 hours ahead while the US is on daylight time. 9:00 AM in Jakarta is 9:00 PM the previous evening in New York in January and 10:00 PM in July.
One country, three clocks
Indonesia stretches across more than 5,000 kilometers and uses three time zones. WIB, Western Indonesia Time (UTC+7), covers Sumatra, Java including Jakarta, and western and central Kalimantan. WITA, Central Indonesia Time (UTC+8), covers Bali, Sulawesi and Nusa Tenggara. WIT, Eastern Indonesia Time (UTC+9), covers Maluku and Papua. None of them uses daylight saving.
Travelers often assume Bali is on Jakarta time. It is not: Bali is one hour ahead of Jakarta, so from New York it is 13 hours ahead in winter and 12 in summer. Check which zone a hotel, ferry or flight time is quoted in before booking connections between islands.
Meeting times that work on both sides
There is no shared office hour. The least painful options:
- 8:00 AM WIB9:00 PM ESTearly for WIB
- 6:00 PM WIB7:00 AM ESTlate for WIB
Factories, coffee and Ramadan hours
Indonesia makes a large share of the sneakers and apparel sold by American brands, and Java and Sumatra export coffee, rubber and palm oil to the US. Buyers in New York reach Indonesian suppliers in the American evening: 8:00 to 10:00 PM Eastern is 8:00 to 10:00 AM in Jakarta in winter, and in summer the same Jakarta morning lines up with 9:00 to 11:00 PM Eastern.
Plan around the Islamic calendar too. During Ramadan many offices shorten the workday, and the Eid al-Fitr holiday, known locally as Lebaran, brings a mass journey home that slows business for one to two weeks. Both move about 11 days earlier each year. Jakarta is already on the next date once it is past noon in New York in winter, or 1:00 PM in summer; the time zone converter handles other dates and cities.

- 9:00 PM the previous evening in winter and 10:00 PM the previous evening during US daylight time.
