UTC to CDT converter
CDT is 6 hours behind UTC 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.
Daylight saving right now
