IST vs WIB: what's the time gap?
WIB is 1 hour and 30 minutes ahead of IST. In everyday terms, once you know the time on one side you just add 1 hour 30 min to get the other — so a call between Mumbai and Jakarta is always 1 hour 30 min apart.
What's the current time in WIB?
Right now the time in Western Indonesian Time (WIB) is Tuesday, June 30, 2026 · 12:54:01 AM. It ticks every second, so you’re always looking at the live WIB clock.
And what time is it in IST?
And in India Standard Time (IST), it’s currently Monday, June 29, 2026 · 11:24:01 PM. Compare the two and the 1 hour 30 min gap is easy to see.
What's the best time for a IST–WIB call?
For example, a 9:00 AM IST meeting takes place at 10:30 AM WIB. The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.
Does daylight saving time change the IST–WIB difference?
The labels IST and WIB are fixed offsets, so the result on this page is always exact. Neither side changes its clocks for daylight saving, so the difference you see here is the same in summer and winter.
How accurate is this IST to WIB conversion?
We don’t guess. IST and WIB times are worked out from the official IANA time zone database, the trusted standard that operating systems use worldwide. Because daylight-saving rules and regional offsets do change over time, we track those updates rather than relying on a fixed number — which is exactly where many converters slip up.
