Frequently Asked Questions
What is an IANA time zone?
An IANA time zone is a standardized identifier maintained by the Internet Assigned Numbers Authority, such as America/New_York or Asia/Shanghai, that represents a specific geographical region with consistent timekeeping rules including daylight saving time.
How is daylight saving time handled?
The tool uses your browser's built-in Intl.DateTimeFormat API which automatically accounts for daylight saving time (DST) transitions for each IANA time zone, so conversions remain accurate throughout the year.
