I have four calendars in my home that say that day light savings time starts on March 11 or April 1. When does it start? Why have these calendar printers put two different dates on these calendars, I wonder?

MIKE MOSS SAYS:     Gail,     The March 11th date is the correct one, due to a recent law that extended Daylight Saving Time by about four extra weeks this year. While the old daylight saving schedule ran from the first Sunday of April to the last Sunday of October, the new one runs from the second Sunday of March to the first Sunday of November. This year that means from 11 March to 4 November.

Apparently your calendars had to be printed before the changes were finalized, or perhaps the calendars are marked for use throughout North America, as Canada will join the U.S. in using the revised DST period, while Mexico will continue to use the old dates so that DST will start there on 1 April.
