Convert the date as well as the hour
A time difference depends on the date. Daylight saving changes can shift it, while travel across midnight can put the same moment on different calendar days.
The converter checks the local time against browser time zone rules. A missing clock time produces an error. If a time occurs twice during a clock change, choose its first or second occurrence.
How to use this tool
- Choose the source and destination time zones.
- Enter the date and time in the source zone.
- Read the converted date and time in the destination zone.
Example
India is 5 hours 30 minutes ahead of UTC. A source time of 10:00 in UTC is 15:30 in Asia/Kolkata on the same day.
Common questions
Why do I need a date?
The offset for a location can change through the year. The date lets the converter apply the rules for that particular moment.
What is a repeated hour?
When clocks move back, some local times occur twice. The first and second occurrences represent different real moments.
