When Does the Time Change in Mexico?

Economic Impact of DST in Mexico

The economic implications of Daylight Saving Time in Mexico are significant and multifaceted. Retail businesses often report increased sales during DST months due to extended evening daylight hours, which encourages shopping and dining out. The tourism and recreation industries particularly benefit, with golf courses, theme parks, and other outdoor venues seeing revenue increases of up to 6%.

However, the transition periods create temporary disruptions. Studies estimate that the Monday following the spring time change results in approximately $581 million in lost productivity nationwide due to sleep deprivation and adjustment issues.

Technology and Time Changes in 2025

Modern devices handle DST transitions automatically, but some systems still require manual updates. In 2025, ensure your smart home devices, car navigation systems, and older electronics are properly configured. Many IoT devices now use internet time servers for automatic updates, reducing the burden on users in Mexico.

IT departments should be particularly vigilant about server time synchronization, especially for systems handling financial transactions or time-sensitive operations.

Agricultural Considerations

Farmers in Mexico have historically had mixed feelings about DST. While the original justification for DST included giving farmers more daylight hours, modern farming practices rely heavily on the sun's position rather than clock time. Dairy farmers particularly note that cows don't adjust their biological clocks, creating temporary disruptions in milking schedules.
