Time Zone Converter FAQ
Is my data sent to a server when converting time?
No. All timezone conversions are computed directly in your browser. No account needed.
Does the converter account for daylight saving time?
Yes. DST is automatically detected and displayed for both source and target timezones. The time difference calculation always reflects the current DST status.
How accurate is the conversion?
The converter is based on the official timezone database, which includes historical DST rule changes. Conversions are accurate for any date from 1970 to the present and future.
Can I quickly swap source and target timezones?
Yes. Click the swap button between the source and target fields to instantly reverse the conversion direction.
What is UTC time and why is it shown?
UTC (Coordinated Universal Time) is the primary time standard used worldwide. Showing UTC alongside the conversion gives you a universal reference point that is unaffected by DST.
