A time zone converter is a tool that translates a specific date and time from one region of the world (a "source" time zone) into the equivalent local time in one or more other regions. It automatically accounts for UTC offsets and Daylight Saving Time (DST), so you always see the correct local time — no mental math required.
Our converter uses the industry‑standard IANA Time Zone Database (via the Intl API) to handle all 50+ time zones, fractional offsets like UTC+5:30 (India) or UTC+5:45 (Nepal), and DST transitions in real time.
Find a time that works for participants in New York, London, and Tokyo simultaneously — without accidentally scheduling at 3 AM for someone.
Know exactly what time you'll land in your destination city, how long your layover is in local time, and when to take medication during long-haul flights.
Manage distributed teams across the Americas, Europe, and Asia-Pacific. Determine overlap hours for synchronous communication windows.
Convert broadcast times for sporting events, product launches, or conferences to your local time so you never miss a livestream.
Know when NYSE, London Stock Exchange, Tokyo Stock Exchange, and crypto markets are open in your local time zone.
Confirm flash sale start times, Black Friday deal countdowns, and auction end times that are listed in Pacific or Eastern time.
All time zone arithmetic revolves around UTC as the universal reference point.
UTC = Local Time − UTC OffsetThe source local time is converted to UTC by subtracting the source zone's UTC offset. For example, 3:00 PM in New York (UTC−4 during EDT) → 3:00 PM − (−4h) = 19:00 UTC.
Target Local = UTC + Target OffsetThe UTC time is converted to each target zone by adding that zone's offset. 19:00 UTC → London (UTC+1 BST) = 20:00 · Tokyo (UTC+9 JST) = 04:00 next day.
DST = Jan offset ≠ Jul offset AND current = max(Jan, Jul)DST is detected by comparing the zone's UTC offset in January vs July. If they differ and the current offset equals the larger value, DST is active.
Offset = ±HH:MM (e.g. +05:30, +05:45, +09:30)Some time zones use 30 or 45‑minute offsets: India (UTC+5:30), Nepal (UTC+5:45), Iran (UTC+3:30), Australia/Adelaide (UTC+9:30). These are handled precisely by our Intl API integration.
