Timezone Converter
TimeConvert times between world timezones using the Intl API
Enter a time in one timezone and pick another, and the converted local time comes back correctly accounting for daylight saving, including checking whether a specific date actually falls during DST in a given region, which matters if you're about to hardcode an offset somewhere. It's built on the browser's Intl API with IANA timezone data, which tracks each region's DST rules and historical changes far more reliably than a fixed UTC offset would. Fixed offsets break twice a year in DST-observing regions and silently drift when a region changes its rules over time, which is exactly why storing an IANA timezone name like `America/New_York` is the safer pattern in your own code. It also handles comparing three or more timezones at once for scheduling a call across a distributed team. The full IANA timezone database is covered, kept current through your browser and OS updates, and nothing is sent anywhere.
