How It Works
Coordinating across time zones — for meetings, calls or flights — means adding the difference between each zone’s offset from UTC. This converter does that automatically for a curated list of major zones, from India (IST) and UTC to New York, London, Dubai, Singapore, Tokyo and Sydney. Enter a time and the source and target zones, and it computes the equivalent time in the destination, using each zone’s current UTC offset — including daylight saving where it is in effect today. Because zones can be more than a day apart in local clock terms, it also flags when the converted time falls on the previous or next day, so you do not schedule a call for the wrong date. Time zones are political as much as geographical, and daylight-saving rules change, so for a specific future date always double-check, but for planning around today this gives you the answer instantly.
Formula
Target time = Source time + (Target UTC offset − Source UTC offset). Offsets use each zone’s current rules, including daylight saving.
Frequently Asked Questions
How do I convert time between two time zones?
Add the difference in their UTC offsets to the source time. This converter does it for you — pick the time, the source zone and the target zone, and it shows the local time there, including any day change.
Does it account for daylight saving time?
Yes — it uses each zone’s current UTC offset, which includes daylight saving where it is in effect today. For a specific future date, DST transitions may shift the offset, so verify for far-ahead scheduling.
What is the time difference between India and New York?
India (IST) is UTC+5:30. New York is UTC−5 (or −4 during daylight saving), making IST about 9.5 to 10.5 hours ahead. The converter shows the exact current difference.
Why does the result show a different day?
Because large offset differences can push the local time past midnight. The converter flags “+1 day” or “−1 day” so you schedule for the correct calendar date, not just the right time.
