Most of Mexico doesn’t have DST.
However, the change has caused confusion and logistical challenges along the US border.
Northern Mexican border towns and cities, such as Tijuana and Juárez (Ciudad Juárez), continue to follow the DST schedules of the USA and Canada. As a result, they will also begin DST on March 9, 2025.
Also starting DST on March 9 are Cuba, Bermuda, The Bahamas, Saint Pierre and Miquelon, and Thule Air Base in Greenland.
Most of Europe begins DST three weeks later, on March 30, 2025.
The Energy Policy Act of 2005, signed by President George W. Bush, extended Daylight Saving Time to 238 days per year, starting in 2007. This change provided Americans with more evening daylight for most of the year. By comparison, Daylight Saving Time in Europe lasts 210 or 217 days per year, depending on the calendar year.
Daylight Saving Time (DST) shifts the local sunrise and sunset times forward one hour, resulting in more evening daylight. To remember which way to set your watch, keep in mind one of these sayings: “spring forward, fall back” or “spring ahead, fall behind.”
The clocks spring ahead (= losing one hour) in the spring when DST starts, and they fall behind one hour (= gaining one hour) when DST ends in the fall.
