It's not quite spring yet, but Daylight Saving Time (DST) begins Sunday morning at 2am in most of the United States and Canada.

The last round of Daylight Saving Time ended about four months ago, on November 7th, 2011.

In the United States of America, Arizona (except for the Navajo Nation), Hawaii, Guam, Puerto Rico, U.S. Virgin Islands, American Samoa and the Commonwealth of the Northern Mariana Islands do not currently observe DST.

Daylight Saving Time ends this year about eight months from now on Sunday, November 4th, when clocks roll back one hour.
