About the Time Zone Converter
India Standard Time (IST) at UTC+5:30 is a 30-minute offset, which confuses scheduling with the many regions that use whole-hour offsets. When your team spans Mumbai, Dubai, London, New York, and Singapore, getting meeting times right is essential. Daylight Saving Time adds another layer of complexity - the US and Europe shift clocks twice a year, changing the IST offset by 1 hour at those boundaries.
Timezone Conversion
Target time = Source time + (Target UTC offset) - (Source UTC offset)
IST = UTC+5:30 · Dubai = UTC+4 · London (GMT) = UTC+0 (UTC+1 in BST) · New York (EST) = UTC-5 (EDT = UTC-4 in summer) · Singapore = UTC+8 · Sydney (AEST) = UTC+10 (AEDT = UTC+11 in summer)
Worked Example
Bangalore meeting at 10:00 AM IST - what time for New York and London colleagues?
New York: 10:00 AM - 10h 30min = 11:30 PM (previous day) · London: 10:00 AM - 5h 30min = 4:30 AM · Best overlap window for all three: 5:30 PM IST
Tips & Insights
- 1
India is unique with a UTC+5:30 offset - always double-check IST conversions as the 30-minute offset is non-intuitive.
- 2
US Daylight Saving Time starts second Sunday in March and ends first Sunday in November - New York shifts from UTC-5 to UTC-4 during this period.
- 3
When scheduling international meetings, find the overlap window first rather than converting one direction only.
- 4
Meeting scheduling tools like Calendly and World Time Buddy handle DST automatically - use them for recurring meetings.
Why this matters for you
India's IT and outsourcing industry works across multiple time zones daily, and scheduling errors cost real time and professional credibility. The IST half-hour offset causes persistent confusion - a 5:30 PM IST call translates to 8:00 AM EST (comfortable) or 7:00 AM GMT (barely acceptable) - understanding these differences makes scheduling genuinely considerate of all participants.
