1pm CST is 6:00 pm UTC
1pm CDT is 6:00 pm UTC in Coordinated Universal Time. UTC is 5 hours ahead of CST today, and that gap changes during the year, so this is recomputed rather than assumed.
What time is 1pm CST in UTC?
It is 6:00 pm. UTC is 5 hours ahead of Central, so you add 5 hours to 1:00 pm and the date does not change. 1pm is afternoon in Central, the second half of the working day, while 6:00 pm is evening in UTC, dinner and the end of the working day.
Spoken as military time, 1pm is 1300 hours and the result is 1800 hours. The military convention exists precisely because "3 o'clock" is ambiguous twice over: once on the 12 hour clock and once across zones.
1pm CST to UTC in the hours either side
The four hours before and after 1pm, in case the meeting moves. The whole window stays on the same day in UTC, so only the hour changes.
| CST | UTC | UTC date | Working hours |

| 9:00 am | 2:00 pm | same day | both sides |
| 10:00 am | 3:00 pm | same day | both sides |
| 11:00 am | 4:00 pm | same day | both sides |
| 12:00 pm | 5:00 pm | same day | CST only |
| 1:00 pm (this page) | 6:00 pm | same day | CST only |
| 2:00 pm | 7:00 pm | same day | CST only |

Is 1pm CST a good time to call UTC?
Marginally. 6:00 pm in UTC is outside the 9:00 am to 5:00 pm working day but still a civilised hour, dinner and the end of the working day. Reasonable for something brief, poor for anything that needs a full room.
Does daylight saving change 1pm CST to UTC?
Yes. Sampled at 1pm on every day of 2026, the gap takes 2 different values. Today it is 5 hours, which is why the answer above is dated rather than fixed.
Central Time is currently on CDT and changes next on Sunday, November 1, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC-5 to UTC-6.
Coordinated Universal Time does not move its clocks at all, so its UTC+0 offset holds every day of the year.
1pm UTC to CST, the other way round
Running the question the other way is a different conversion, not a mirror image, because the two zones can be in different daylight saving states on the same date. 1pm UTC is 8:00 am CST, which is a different reading from the answer above, because the two directions are separate questions. One wrinkle worth knowing: CST and CDT are two names for the same zone, not two zones. Central Time reads CST in winter and CDT in summer. When somebody types "cst to utc" they nearly always mean the zone rather than the literal winter offset, so this page resolves CST to America/Chicago and UTC to Etc/UTC and applies whichever offset is genuinely in force on the day.
