Best time to call Mexico City from Sydney (and vice versa)

With 16 hours between them there is no hour at which Sydney and Mexico City are both inside a 9:00–17:00 working day. Teams split across these two cities usually alternate the sacrifice: one week the meeting lands early (7:00–8:00) in Mexico City and late (18:00–19:00) in the other city, the next week the other way round. The Timezone Matcher grid shades exactly those compromise hours.

Mexico City — America/Mexico_City

Mexico City abolished daylight saving in October 2022 and now stays on UTC−6 all year, so it lines up with Chicago in winter and with Denver in summer.
