Frequently asked
Does this account for daylight saving time?
Yes. The conversion uses your browser's own time zone database (via the Intl API), which already knows each zone's daylight saving rules and transition dates, so the result is correct even across a DST boundary.
Where does the time zone data come from?
It comes from your device's own operating system/browser, the same source used for all date and time formatting on the web. No external service is queried.
Can I convert a past or future date, not just now?
Yes. Change the date field to anything else. This matters for time zones whose offset changes at different points in the year.
