Free Time Zone Converter
Schedule across the planet without the mental gymnastics — convert any moment between time zones instantly.
Converted time
Daylight saving is handled automatically for the date you pick.
How to use the time zone converter
- Pick the date and time of your event, or hit Use current time.
- Choose the time zone that time is in (From) and the one you want to convert to (To).
- Read the converted time — the live line underneath always shows what time it is right now in both zones.
- Use Swap zones to flip the conversion around instantly.
Beating time zone confusion
Most scheduling mishaps come from daylight saving, not from the zones themselves: New York is five hours behind London in winter but only four in the weeks when their DST transitions do not line up, and southern-hemisphere zones like Sydney flip the other way entirely. This converter applies the correct offset for the exact date you enter, so those edge weeks are handled. When you send a meeting invite, always include the time zone explicitly ("3pm ET") or, better, the UTC equivalent — "15:00 UTC" is unambiguous everywhere and immune to everyone's local DST rules. For recurring meetings across zones, pick a time that is humane for all sides rather than defaulting to your own 9am; rotating the inconvenience quarterly keeps distributed teams happy. And remember that some regions observe half-hour or 45-minute offsets (India, Nepal, parts of Australia), so never assume every zone differs by a whole hour.
Frequently asked questions
Does this handle daylight saving time?
Yes. Conversions use the real offset rules for the date you enter, including DST transitions in both zones.
What is the difference between EST and ET?
EST is Eastern Standard Time (UTC−5); ET means "Eastern Time" and follows whichever is in effect — EST in winter, EDT (UTC−4) in summer. Prefer ET/PT-style labels.
Why do meeting times sometimes shift by an hour?
Usually a DST transition in one zone but not the other. Converting against the specific event date, as this tool does, avoids the trap.
What does UTC mean?
Coordinated Universal Time — the global reference clock with no daylight saving. All time zones are defined as offsets from UTC.
