Spot Date-Line Shifts at a Glance

Late-night ist times can land on a different date in wib because of the 1 hours and 30 minutes offset. The converter labels "next day" or "previous day" next to the result so you never send a message a day early or miss a deadline.

The two zones in context

IST vs WIB — cities and working rhythm

IST — India Standard Time
Primary cities: Mumbai, Delhi, Bengaluru, Hyderabad, Chennai, Kolkata

Indian business hours run 10 AM – 7 PM IST typically; IT / BPO shifts commonly extend to cover US and UK working hours, so 3:30 PM – 12:30 AM IST (US overlap) and 12:30 PM – 9 PM IST (UK overlap) are the two second shifts you see most often. Weekend is Saturday-Sunday for most private-sector employers.
