The time zone converter changes a date and time from one time zone to another and shows the difference in hours between them. It's ideal for scheduling calls, meetings and travel across regions.
How it works
The tool uses your browser's built-in internationalisation engine, which knows global time zones and their current offsets. Because it relies on up-to-date zone data, it accounts for Daylight Saving Time where it applies.
How to use it
Enter the date and time to convert.
Select the source time zone.
Select the destination time zone.
Convert to see the local time and the difference.
Tips for working across time zones
Always confirm AM/PM or use 24-hour time to avoid mix-ups.
Remember that Daylight Saving shifts can change the difference at certain times of year.
For recurring meetings, agree on a single reference zone (often UTC).
Frequently Asked Questions
Does this account for Daylight Saving Time?
Yes. It uses current time-zone data from your browser, which includes Daylight Saving Time rules where they apply.
What is UTC?
UTC (Coordinated Universal Time) is the global time standard that time zones are defined against; it does not observe Daylight Saving.
Why does the time difference change during the year?
Because some regions move their clocks for Daylight Saving Time, the gap between two zones can shift by an hour seasonally.
Does this tool store my data?
No. Everything runs entirely in your browser. Nothing you enter is uploaded, saved, or shared.
