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:
“For us necessity is not as of old an image without us, with whom we can do warfare; it is a magic web woven through and through us, like that magnetic system of which modern science speaks, penetrating us with a network subtler than our subtlest nerves, yet bearing in it the central forces of the world.”
—Walter Pater (1839–1894)
“This, our respectable daily life, on which the man of common sense, the Englishman of the world, stands so squarely, and on which our institutions are founded, is in fact the veriest illusion, and will vanish like the baseless fabric of a vision; but that faint glimmer of reality which sometimes illuminates the darkness of daylight for all men, reveals something more solid and enduring than adamant, which is in fact the cornerstone of the world.”
—Henry David Thoreau (1817–1862)
“They were regular in being gay, they learned little things that are things in being gay, they learned many little things that are things in being gay, they were gay every day, they were regular, they were gay, they were gay the same length of time every day, they were gay, they were quite regularly gay.”
—Gertrude Stein (1874–1946)
