Best Meeting Time: Mexico City to Chicago

Mexico City and Chicago share the same standard offset (UTC–6), which makes scheduling straightforward for much of the year. The complication arrives in spring and autumn: Mexico discontinued daylight saving in 2022, while Chicago still observes it. That creates a one-hour gap between mid-March and early November, with Chicago ahead. Teams in both cities work 9am–6pm, yielding an 8-hour overlap when aligned and 8 hours (10am–6pm Chicago, 9am–5pm Mexico City) when Chicago shifts forward. Long business lunches in Mexico City, often stretching from 2pm to 4pm, mean late-afternoon slots in Chicago sometimes reach voicemail.

Time Difference: Mexico City and Chicago

Chicago is currently 1 hour ahead of Mexico City. The live offsets are Mexico City UTC-6 and Chicago UTC-5. Mexico City does not observe daylight saving and Chicago observes daylight saving, so the offset shifts twice a year if both sides aren't already aligned.

Mexico City holds UTC–6 year-round since the country ended daylight saving. Chicago moves to UTC–5 in mid-March and back to UTC–6 in early November. During those eight months Chicago runs one hour ahead; outside that window the cities share identical local time. The gap widens from 0 to 1 when Chicago springs forward and narrows back to 0 when it falls back.

Best Times to Meet

Inside that 8-hour window, the cleanest slot is typically 10am–1pm Chicago (9am–12pm Mexico City). It avoids the extended lunch culture in Mexico City, which often reserves 2pm–4pm for formal meals, and respects Chicago's early-start trading culture: CME and CBOE desks open at 7am Central, so by 10am the first wave of meetings has cleared. Late-afternoon calls (4pm–5pm Chicago, 3pm–4pm Mexico City) work if both teams skip the traditional lunch break, but expect lower attendance in Mexico City. When the cities align perfectly in winter, any hour from 9am to 5pm works without translation.

Tips for Scheduling Across Mexico City and Chicago

• When Chicago observes DST, subtract one hour from your Mexico City clock to find Chicago time; otherwise the cities match.
• Schedule around Mexico City's 2pm–4pm lunch window; Chicago colleagues dialling in at 3pm local will find fewer picks-up.
• Chicago's winter remote-work bias (December–February) means video calls often replace in-person loops; confirm attendance early.
• CME trading desks open at 7am Central; financial teams in Chicago may prefer 10am starts to clear internal stand-ups first.
• Check both Independence Day calendars: Mexico celebrates 16 September, the US 4 July; neither is a shared downtime.

Public Holidays and Working Weeks

Both cities observe a Monday–Friday working week with 9am–6pm hours. Mexico City's next major public holiday is Independence Day on 16 September, followed by Day of the Dead on 2 November. Chicago marks Independence Day on 4 July and Thanksgiving on the fourth Thursday in November. Cross-city meetings should check both calendars; a routine Tuesday in Chicago may fall on Guadalupe Day (12 December) in Mexico City, closing banks and government offices.
