ART to UTC converter
UTC is 3 hours ahead of ART right now. Live clocks on both sides, a direct time input, the full 24-hour table with a permalink per hour, and the real daylight-saving state — computed from the IANA tz database on every request, never from a stored offset.
Convert an exact time type it — no sliders
Conversion runs in your browser against the same IANA rules the server uses, so it keeps working offline and nothing you type is sent anywhere.
