UTC to CDT converter

CDT is 5 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.

Daylight saving right now

Central Daylight Time

America/Chicago is currently on CDT (UTC-05:00), its daylight-saving clock.

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

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.

Coordinated Universal Time

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

no clock change scheduled — fixed at UTC+00:00

UTC to CDT — questions

What time is it in CDT when it is UTC now?
CDT is currently 18:25 on Wednesday, 12 August 2026 (CDT, UTC-05:00), while UTC is 23:25 (UTC+00:00). That is 5 hours behind the source clock right now.
How many hours behind is CDT of UTC?
5 hours at this moment. The gap is not constant across the year: Coordinated Universal Time and Central Daylight 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 CDT on daylight saving time right now?
Yes — America/Chicago is on CDT (UTC-05:00) right now.
When does CDT next change its clocks?
America/Chicago next changes on Sunday, 01 November 2026 at 01:00 local time, when it moves back 60 minutes and the abbreviation becomes CST (UTC-06:00). That is 80 days away. This date comes from the IANA tzdata rules currently in force, so it updates if a government changes the law.
What is the best time to schedule a call between UTC and CDT?
There are 4 hours of overlap where both sides are inside a 09:00-18:00 working day. The longest block is 14:00–18:00 UTC, which is 09:00–13:00 CDT. 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 CDT in code?
Use America/Chicago. Abbreviations like CDT 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-05:00 instead will be wrong the moment the rules change.
