Mexico City and Sydney: plan a meeting across time zones

The time difference

For most of the year, Sydney is 16 hours ahead of Mexico City. That gap does not hold all year — here is how it actually moves:

• 1 January to 4 April: Sydney is 17 hours ahead of Mexico City
• 5 April to 3 October: Sydney is 16 hours ahead of Mexico City
• 4 October to 31 December: Sydney is 17 hours ahead of Mexico City

Best time to meet

Mexico City and Sydney do not share a normal working-hours window. The best compromise is 4:30 PM in Mexico City / 8:30 AM in Sydney — still early or late for whoever is furthest from a normal day, which is the honest trade-off at this distance.
