Begins March 9th in the US. How about Mexico? My flight times are really odd, but I guess that is why.
In recent years there has been a weeks difference between Mexico and the US. I'm not 100% sure of the exact date this year though.
Since 2007 Mexico has been out of sync with the US. The airlines HATE this. In the US Daylight Savings Time beings on the 2nd Sunday in March. In Mexico it begins the first Sunday in April, so it begins Sunday, April 5, 2009 at 1:59:59 AM.
one thing I LOVE about Mexico. . .seriously. . .rules, directions, laws, arrangements, guidelines, etc. . . are kinda dynamic. sorta like the lines to customs at the airport. . .
