  • Finding shared working hours: both Chicago and Peru are inside the 9-to-5 working day between 9:00 AM and 5:00 PM CDT time (9:00 AM–5:00 PM PET). That is roughly 8 hours of usable overlap.
  • Keeping family and friends in sync: knowing that 8:00 PM in Chicago is 8:00 PM in Peru makes it easy to avoid calling at 3 AM.

  • Chicago: Clocks fall back on Sun, Nov 1, 2026. Re-check this page after that date because the offset changes and so does the +0h gap.
