It’s almost time for a time change.

Most people in Mexico will set their clocks ahead one hour before heading to bed Saturday night.

If you forget which way to move the clock, remember the old adage, “spring ahead” and “fall back.” Hint: We’re in spring.

The time change officially happens at 2 a.m. Sunday, April 5. DST began in U.S. and Canada almost two weeks ago. Everyone loses an hour during the spring time change.

The states of Quintana Roo and Sonora do not observe Daylight Saving Time, maintaining a single time zone throughout the year. Sonora aligns its clocks with neighboring Arizona, which also ignores DST.

Quintana Roo stays on Eastern Standard Time to match the clocks in other Caribbean tourist destinations that compete with the Riviera Maya.

When Yucatán enters DST, its clocks will match Quintana Roo’s until the last Sunday of October, when clocks in Yucatán retreat an hour again.

We get that lost hour back when DST ends in the U.S. and Canada on Sunday, Nov. 4 and in most of Mexico on Sunday, Oct. 28.
