Understanding the +6h Gap: Chicago vs WAT

Chicago runs on Central Daylight Time (CDT) at UTC-05:00, currently observing daylight saving time. WAT runs on West Africa Time (WAT) at UTC+01:00. That puts Chicago 6 hours ahead of WAT — a difference of +6h at the current offsets.

In practice, when it is 9:00 AM in Chicago it is 3:00 PM in WAT. Midnight in Chicago is 6:00 AM in WAT.Chicago observes daylight saving time while WAT does not, so the gap narrows or widens by an hour part of the year.

Why people convert Chicago to WAT time

  • Scheduling a call from Chicago to WAT: a 10:00 AM start in Chicago lands at 4:00 PM in WAT, so you can confirm the slot without doing the arithmetic yourself.
  • Finding shared working hours: both Chicago and WAT are inside the 9-to-5 working day between 9:00 AM and 11:00 AM CDT time (3:00 PM–5:00 PM WAT). That is roughly 2 hours of usable overlap.
  • Coordinating a Chicago-based team with WAT contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
  • Always state the zone abbreviation, not just the hour. "3:00 PM CDT" is unambiguous; "3 PM" across a +6h gap is not.
  • Block 9:00 AM–11:00 AM CDT as the recurring meeting window if you work primarily from Chicago and need WAT colleagues present.
  • Chicago: Clocks fall back on Sun, Nov 1, 2026. Re-check this page after that date because the offset changes and so does the +6h gap.

About CST (Central Standard Time)

About WAT (West Africa Time)

West Africa Time (WAT) is used across much of West and Central Africa, including Nigeria, the most populous country in Africa. WAT does not observe daylight saving time and shares the same offset as Central European Time (CET).
