FAQ
Q1
Is daylight saving time (DST) reflected automatically?
Yes. The tool uses the browser's Intl API, which handles DST transitions automatically.

Is there a limit to how many cities I can add?
30 cities are available as presets (6 default + 24 additional). Use 'Reset to default' to restore the initial set.
