Example: meeting across US Eastern and China
You schedule March 10, 9:00 AM in New York (US Eastern). Convert to Asia/Shanghai to see the equivalent clock time for colleagues—often the same calendar evening or the next morning, depending on DST. For duration only (no zones), use the time difference calculator.
Time zones vs. date-only tools
This page needs a zone + clock time. If you only move calendar dates without times, use add/subtract date or date difference. All listed zones use standard IANA names; rules update with your browser.
