This time zone converter lets you compare current times across multiple cities simultaneously, scrub through a 24-hour timeline to find meeting overlap, and share time zone views with a link. All conversions use IANA time zone data with automatic daylight saving time handling, so offsets are always accurate regardless of the time of year.
Find the UTC offset for both time zones, then add or subtract the difference. Example: 3 PM New York (UTC-5 EST) to London (UTC+0 GMT) = 3 PM + 5 hours = 8 PM London. During DST: New York becomes UTC-4 (EDT) and London becomes UTC+1 (BST), so the gap narrows to 5 hours. This tool handles all DST transitions automatically.
New York ↔ London: 9 AM–1 PM ET / 2–6 PM GMT. London ↔ Dubai: 9 AM–5 PM GMT / 1–9 PM GST. London ↔ Singapore: 9–10 AM GMT / 5–6 PM SGT (very narrow). New York ↔ Singapore: 8–9 AM ET / 9–10 PM SGT. New York ↔ Sydney: 7–8 PM ET / 9–10 AM AEST (next day). For three-continent meetings, consider rotating the inconvenient time slot.
