Time Zone Converter
Convert a date and time from one time zone to another, with daylight saving handled automatically.
Pick a date, time, and two zones to convert.
How to use the time zone converter
Set the date and time you have in mind, choose the zone it belongs to in the "from" menu, and pick the zone you want in the "to" menu. The converted time appears with the full date, so you can see at a glance when the result lands on a different day.
The "from" zone starts on your own zone, detected from your device, so the common case of "what time is this for someone over there" takes two clicks. The swap button flips the two zones if you want to read the conversion the other way around.
Daylight saving is handled for you
Many regions shift their clocks forward in spring and back in autumn, and they do not all switch on the same date. That makes manual conversion error-prone, since the gap between two cities can change by an hour depending on the time of year.
This converter reads each zone's rules for the exact date you enter, so a meeting in March and the same meeting in July convert correctly even if one city has changed its clocks and the other has not. You do not need to track the switch dates yourself.
When the date changes across zones
Zones far apart can sit on different calendar days at the same moment. An evening call in Los Angeles can be the following morning in Tokyo, and a morning meeting in Sydney can still be the previous day in New York. Because of this, the converter always shows the full weekday and date next to the time.
Watching the date as well as the clock avoids the classic scheduling slip of booking something for the right hour on the wrong day. It is the detail that matters most when the two zones are more than half a world apart.
Planning meetings and travel
For a call with colleagues abroad, enter your local time and convert it to their zone to confirm it falls inside their working hours. For travel, convert your departure and arrival times to the destination zone so an itinerary reads in local time end to end.
The converter covers a spread of widely used zones across the Americas, Europe, Asia, and the Pacific, each with a plain-language label, so you do not have to remember which IANA name maps to which city.
Frequently asked questions
- How do I convert a time between two time zones?
- Enter the date and time, set the zone it belongs to in the from menu, and choose your target zone in the to menu. The converted time and full date appear right away, including a different calendar day if the conversion crosses midnight.
- Does the converter handle daylight saving time?
- Yes. It reads each zone's daylight saving rules for the specific date you enter, so conversions stay correct whether the date falls inside or outside a region's summer time, even when two cities switch on different days.
- Why does the result sometimes show a different date?
- Zones far apart can be on different calendar days at the same instant. An evening in one city can be the next morning across the world, so the tool always shows the weekday and date alongside the time to avoid scheduling on the wrong day.
- How does the tool know my time zone?
- It reads the zone set on your device through your browser and uses it as the default from zone. You can change it to any zone in the list, and if your zone is not already there it is added to the menu.
- Which time zones are supported?
- The menu includes commonly used zones across the Americas, Europe, Asia, and the Pacific, plus UTC, each labeled with a familiar city name. Your own device zone is added automatically if it is not already on the list.
