About this tool
This page opens the converter with UTC as the source and New York as the target — the current UTC moment is shown in New York local time immediately, and you can enter any timestamp you need to decode.
UTC never changes, but New York does: it observes EST (UTC−5) in winter and EDT (UTC−4) in summer. That is exactly why server logs, API timestamps, flight schedules and release times are published in UTC — and why converting them to Eastern time needs the right seasonal offset, which this tool takes from the IANA zone rules for the specific date.
The full tool converts between any two time zones, not just UTC and New York, and runs completely locally — no timestamp ever leaves your browser.
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.
