Three numbers. The ones that decide the meeting.
When the world meets at work.
Read the day in both zones.
Crossing the border. Money, language, plugs.
Money changes hands at the border: Bengaluru uses the INR (₹) and Surabaya uses the IDR (Rp). Language shifts too — English in Bengaluru, Indonesian in Surabaya. Cars drive on the left in both, so rentals feel familiar.

Quick answers. Before you book the call.
What's the time difference between Bengaluru and Surabaya?
Bengaluru is 1.5 hours ahead of Surabaya. Bengaluru runs on GMT+5:30 and Surabaya on GMT+7. The gap can shift by an hour when either side enters or leaves daylight saving — the live clocks above always reflect the current offset.
When's the best time to schedule a meeting?
There are 7 hours where both cities are inside a 09:00–17:00 workday. Aim for the middle of that window so neither side is starting or closing out.
Does daylight saving time change the difference?
Yes, if either city observes DST. When one side shifts and the other doesn't, the gap changes by one hour. The DST badges under each clock show whether each zone is currently shifted and when the next transition lands.
