About this tool
This page opens the time zone converter with India preselected as the source and New York as the target — a live conversion is shown immediately, ready for the exact date and time of your call or deadline.
India runs on IST, a fixed UTC+5:30 with no daylight saving, while New York is UTC−5 in winter (EST) and UTC−4 in summer (EDT). New York is therefore 10:30 or 9:30 behind India depending on the season — a late-evening call in India lands in the New York morning. The IANA zone data picks the right offset for your chosen date.
The full tool goes beyond this pair: pick any two zones on Earth, swap direction with one click, and convert entirely locally — nothing is sent to a server.
Example. 12:00 in America/New_York on 15 January 2026 is 22:30 in Asia/Kolkata, GMT+05:30. On 15 July 2026 the same clocks read 21:30.
Limit. 02:30 in New York on 8 March 2026 does not exist and is rejected. The fall-back hour resolves to one instant. Zones come from the browser's IANA list.
