IST to Dubai: quick answer
To convert India Standard Time to Dubai time, subtract 1 hour and 30 minutes. For example, 10:30 AM IST is 9:00 AM in Dubai. India Standard Time is UTC+05:30, while Dubai uses Gulf Standard Time at UTC+04:00.
The difference remains 1 hour and 30 minutes throughout the year because neither India nor Dubai currently changes clocks for daylight saving time.
How to convert IST to Dubai time
- Start with the India Standard Time date and time.
- Subtract 1 hour and 30 minutes.
- If the result moves before midnight, use the previous date in Dubai.
- Label the result as Dubai time or Gulf Standard Time.
Example: 12:45 AM IST – 1 hour 30 minutes = 11:15 PM in Dubai on the previous calendar date.

The converter uses the IANA identifiers Asia/Kolkata and Asia/Dubai. It retains the selected date so early-morning IST values produce the correct previous-day result in Dubai.

Best India-to-Dubai meeting window
A practical shared 9-to-5 business-hours window is 10:30 AM-5:00 PM IST, corresponding to 9:00 AM-3:30 PM in Dubai. An Indian workday ending at 6:00 PM corresponds to 4:30 PM in Dubai. Confirm each organization’s working days and local holiday schedule separately.
Formula, methodology and verification
The calculation subtracts India’s UTC offset of 330 minutes from Dubai’s offset of 240 minutes. The resulting difference is -90 minutes, so the converter subtracts 1 hour and 30 minutes. Verification covers half-hour arithmetic, previous-day and year-boundary rollover, 12-hour and 24-hour formats, leap-day dates, and reciprocal IST-to-Dubai-to-IST test cases.
