"Most areas of the United States currently observe daylight saving time (DST), the exceptions being Arizona (except for the Navajo Nation, which does observe daylight saving time), Hawaii, and the overseas territories of Puerto Rico, American Samoa, Guam, the Northern Mariana Islands, and the United States Virgin Islands."
In Canada, "Daylight saving time (DST) is now observed in all Canadian provinces, with the exception of most of Saskatchewan, which observes Central Standard Time year-round even though it is in the Mountain Zone, effectively putting it on DST year round."
Oh, I'm a Wikiman and I'm OK.
