Frequently Asked Questions
How does daylight saving time (DST) work here?
The tool uses the native JavaScript Intl.DateTimeFormat API and your device operating system timezone database, guaranteeing up-to-date daylight saving time offsets.
Will my saved cities be retained when I reload the page?
Yes. Your active city list is preserved in your browser localStorage and mirrored directly in the shareable URL.
Is there a limit to how many time zones I can compare?
No. You can add as many global cities and team locations as needed to coordinate cross-border projects.
