Dubai is 10 hours ahead of Mexico City. Put the other way round: Mexico City is 10 hours behind Dubai.
Mexico City is UTC-6 in summer and UTC-6 in winter; Dubai is UTC+4 and UTC+4.
A nine-to-five in Mexico City and a nine-to-five in Dubai do not overlap at all. Somebody has to move: the nearest workable slots are early morning in one city or late evening in the other, which is the kind of thing the planner is for.
Neither Mexico City nor Dubai changes its clocks, so this gap is the same every day of the year.

This page covers one pair. TimeGap takes a list: add every city you care about, drag one marker, and every row reads the same instant on its own clock. It marks the hours you would actually take a call, finds the window where the most people are reachable, flags public holidays, and puts the time you pick straight into Outlook or Google Calendar.
