Daylight saving time (DST) is in effect in much of the Central time zone between mid-March and early November. The modified time is called Central Daylight Time (CDT) and is UTC−5. In Canada, Saskatchewan does not observe a time change. One reason that Saskatchewan does not take part in a time change is that, geographically, the entire province is closer to the Mountain Time Zone's meridian. The province elected to move onto "permanent" daylight saving by being part of the Central Time Zone. The only exception is the region immediately surrounding the Saskatchewan side of the biprovincial city of Lloydminster, which has chosen to use Mountain Time with DST, synchronizing its clocks with those of Alberta.
In those areas of the Canadian and American time zones that observe DST, beginning in 2007, the local time changes at 02:00 local standard time to 03:00 local daylight time on the second Sunday in March and returns at 02:00 local daylight time to 01:00 local standard time on the first Sunday in November. Mexico decided not to go along with this change and observes their horario de verano from the first Sunday in April to the last Sunday in October. In December 2009, the Mexican Congress allowed ten border cities, eight of which are in states that observe Central Time, to adopt the U.S. daylight time schedule effective in 2010.

Famous quotes containing the words central, daylight and/or time:
“My solitaria
Are the meditations of a central mind.
I hear the motions of the spirit and the sound
Of what is secret becomes, for me, a voice
That is my own voice speaking in my ear.”
—Wallace Stevens (1879–1955)
“Come praise Colonus’ horses, and come praise
The wine-dark of the wood’s intricacies,
The nightingale that deafens daylight there,
If daylight ever visit where,
Unvisited by tempest or by sun....”
—William Butler Yeats (1865–1939)
“The daily arguments over putting away the toys or practicing the piano defeat us so easily. We see them coming yet they frustrate us time and time again. In many cases, we are mothers and fathers who have managed budgets and unruly bosses and done difficult jobs well through sheer tenacity and dogged preparation. So why are we unable to persuade someone three feet tall to step into six inches of water at bathtime?”
—Cathy Rindner Tempelsman (20th century)
