The CalculatorGeek team normalized the legacy route into the shared engine and checked it with five or more deterministic fixtures across January, July, leap day, year end, and the September reference date.
These records describe the published model and reference tests. A test-case count is not a certification of every possible input or an independent specialist review. Editorial policy
Known limitations
- This route treats IST as Asia/Kolkata and GST as Asia/Dubai; the same abbreviation can mean something else elsewhere.
- Supported dates are limited to 1970-01-01 through 2100-12-31 to avoid presenting pre-standard sub-minute historical offsets as modern minute-level precision.
- The meeting window assumes 9:00 AM to 5:00 PM on weekdays in both zones and does not account for holidays or personal schedules.
- Calendar exports preserve the converted UTC instant and the selected event duration.

IST to Dubai: direct answer
Dubai time is 1 hour 30 minutes behind India Standard Time throughout the year. Subtract 1 hour 30 minutes from an IST time and carry any previous-date rollover shown in the result. Reverse the direction with the Dubai to IST Converter, or compare all reviewed routes in the time-zone converter hub.
How the date-aware conversion works
The calculator resolves the selected India Standard Time wall time using Asia/Kolkata, converts it to one UTC instant, and formats that instant using Asia/Dubai. This preserves the selected date, minute precision, seasonal rules where configured, and the target calendar day.
Choose date-aware time or a fixed UTC offset
This page always interprets India as Asia/Kolkata and Dubai as Asia/Dubai. For current dates, India is UTC+05:30 and Dubai is UTC+04:00, so the arithmetic shortcut is India time - 1 hour 30 minutes. The calculator still resolves the selected date through the named IANA zones so the displayed offsets, historical rules and day rollover remain auditable. For an explicitly stated offset instead of a city clock, use the IST to UTC Converter.
Calendar-date rollover
12:30 AM in India Standard Time on December 31, 2026 converts to 11:00 PM in Dubai Time, previous day. Always carry the displayed date into invitations and travel plans.
Daylight saving and offset rules
Neither endpoint in this route has a seasonal abbreviation change in the supplied configuration. IANA-backed endpoints are still resolved by the selected date so historical rule changes are not replaced by a present-day shortcut.
Common IST to GST conversions
These reproducible examples use October 9, 2026 and the named zones Asia/Kolkata and Asia/Dubai.
| India | Dubai | Calendar relationship |
|---|---|---|
| 12:00 AM | 10:30 PM | Previous day |
| 9:00 AM | 7:30 AM | Same day |
| 12:00 PM | 10:30 AM | Same day |
| 5:00 PM | 3:30 PM | Same day |
| 1:00 AM | 11:30 PM | Previous day |
Plan meetings across both zones
For a Monday-to-Friday 9:00 AM-5:00 PM schedule in both places, the shared window is 10:30 AM-5:00 PM in India and 9:00 AM-3:30 PM in Dubai. The planner calculates this from the selected date, checks the full meeting duration, and can add a third IANA zone. Carry the calendar date into the invitation when an early India meeting belongs to the previous evening in Dubai.
Abbreviations and minute precision
This pair has a half-hour component, so rounding to whole hours would produce the wrong minute value. Abbreviations such as IST or GST can identify more than one place; the labels and configured zone or offset on this page control the result. If you intended a different location or abbreviation, choose a location-specific route from the time-zone converter hub.

Frequently asked questions
How far behind India is Dubai?
For current dates, Dubai is 1 hour 30 minutes behind India. This page verifies the selected date through Asia/Kolkata and Asia/Dubai before displaying the result.
Can the date change during this conversion?
Yes. India times from 12:00 AM through 1:29 AM belong to the previous calendar day in Dubai.
Do India or Dubai change clocks seasonally?
Neither configured endpoint observes a seasonal clock change in the supported modern range, but the selected date is still part of the resolved conversion record.
Does IST always mean India?
No. IST is ambiguous. This route explicitly uses India Standard Time through Asia/Kolkata; Dubai is Asia/Dubai.
What date range is supported?
The public input is bounded to 1970 through 2100, where minute-level output does not imply unsupported pre-standard sub-minute precision.
Sources and review
Zone identifiers and rule history use the IANA Time Zone Database, reviewed October 20, 2026 against release 2026e. UTC terminology follows the International Bureau of Weights and Measures. The browser exposes IANA behavior but not its bundled tzdb version. Validation covers the 90-minute difference, half-hour precision, reciprocal conversion, 12:00 AM India rollover, shared working hours and calendar output.
