CST to UTC — Time Zone Converter
Central Time (CST, UTC−6) covers the central United States; Coordinated Universal Time (UTC, UTC+0) covers the global reference timeline. In standard time, UTC is 6 hours ahead of CST. Mornings in the central United States overlap with afternoons in the global reference timeline, which keeps both sides inside office hours. Use the live converter below — it applies today's IANA time zone data, including daylight saving time, and gives you a meeting schedule you can paste straight into email or Slack.
