Convert Time Between Time Zones
Scheduling a call with someone in another country? This time zone converter turns any date and time in one time zone into the matching local time in another. Daylight saving time is handled automatically for the date you choose, and the converter shows clearly when the converted time falls on the previous or next day.
How Time Zone Conversion Works
Every time zone is defined as an offset from Coordinated Universal Time (UTC). For example, New York is UTC−5 in winter and UTC−4 during daylight saving time. The converter finds the UTC moment for your chosen date and time in the "from" zone, then displays that same moment in the "to" zone.
Example: 9:00 AM in New York on a summer day (UTC−4) is 2:00 PM in London (UTC+1) and 10:00 PM in Tokyo (UTC+9).
Tips for Scheduling Across Time Zones
- Always include the time zone in meeting invitations, such as "3:00 PM ET."
- Watch for daylight saving changes. The U.S. and Europe switch on different dates in spring and fall.
- For global teams, look for overlap in working hours before picking a time.
- Some regions, such as India (UTC+5:30) and Nepal (UTC+5:45), use half- or quarter-hour offsets.
Frequently Asked Questions
Does the converter adjust for daylight saving time?
Yes. It uses official time zone rules for the date you enter, so daylight saving time is applied automatically wherever it is in effect.
What is the difference between UTC and GMT?
For everyday purposes they show the same time. UTC is the precise atomic time standard used worldwide, while GMT is a time zone used by the UK in winter. The UK switches to BST (UTC+1) in summer.
Why does my converted time show a different date?
Time zones can be many hours apart, so the same moment can be "today" in one place and "tomorrow" or "yesterday" in another. The converter flags when this happens.
