When the difference changes

Australian Central Time and Central Time – Mexico do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

  1. Now – October 4, 2026Central Time – Mexico is 15 hours 30 minutes behind
  2. October 4, 2026 – April 4, 2027Central Time – Mexico is 16 hours 30 minutes behind
  3. April 4, 2027 – October 3, 2027Central Time – Mexico is 15 hours 30 minutes behind
  4. October 3, 2027 – onwardsCentral Time – Mexico is 16 hours 30 minutes behind

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.

Australian Central Time (ACST) is used in South Australia and the Northern Territory, on a half-hour offset from the east coast

Central Time – Mexico (CST) is used in most of Mexico. Mexico abolished daylight saving in October 2022, so it no longer tracks US Central Time in summer.
