FAQ

Does it account for daylight saving time?

Yes. The converter uses your browser's Intl.DateTimeFormat API, which applies current DST rules for each timezone automatically.

Why does it use a fixed date internally?

DST rules depend on the calendar date. A fixed January reference date is used for consistency — actual offsets during summer may differ by one hour in DST-observing zones.
