CDT to UTC converter

UTC is 5 hours ahead of CDT 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.

Daylight saving right now

Coordinated Universal Time

UTC is currently on UTC (UTC+00:00).

no clock change scheduled — this zone is fixed at UTC+00:00

UTC is the reference clock every other offset is quoted against. It has no daylight saving and never shifts.

Central Daylight Time

America/Chicago is on CDT (UTC-05:00).

next change: Sun, 1 Nov 2026 01:00 local → CST (80 days)

CDT is US Central Time in summer, UTC-5 — the same offset as winter EST, which is a classic source of one-hour scheduling bugs.

Best time to call green = 09:00–18:00 on both sides

4 overlapping working hours. The longest run is 09:00–13:00 CDT, which is 14:00–18:00 UTC.

CDT to UTC — questions

What time is it in UTC when it is CDT now?
UTC is currently 00:15 on Thursday, 13 August 2026 (UTC, UTC+00:00), while CDT is 19:15 (UTC-05:00). That is 5 hours ahead of the source clock right now.
How many hours ahead is UTC of CDT?
5 hours at this moment. The gap is not constant across the year: Central Daylight Time and Coordinated Universal Time change clocks on different dates (or one of them not at all), so a difference you hard-code in summer can be an hour wrong in winter. The table on this page is computed from the current tzdata rules, not from a fixed offset.
Is UTC on daylight saving time right now?
No. UTC is on UTC (UTC+00:00) at the moment.
Does UTC observe daylight saving time?
No. UTC stays on UTC+00:00 all year, so the difference from CDT only moves when CDT itself changes.
What is the best time to schedule a call between CDT and UTC?
There are 4 hours of overlap where both sides are inside a 09:00-18:00 working day. The longest block is 09:00–13:00 CDT, which is 14:00–18:00 UTC. Use the calendar buttons above to drop it straight into Google Calendar, Outlook or an .ics file.
Which IANA timezone name should I use for UTC in code?
Use UTC. Abbreviations like UTC are ambiguous and not resolvable by most libraries — Python's ZoneInfo, Java's ZoneId, Go's time.LoadLocation and JavaScript's Intl all expect the IANA name. Hard-coding UTC+00:00 instead will be wrong the moment the rules change.
