Did you know that peak UV times can be read from our sunrise/sunset tables? Simply look for the time given in the Solar Noon column. That coincides with peak UV time.

Daylight Saving Time 2011
For those of you in North American jurisdictions that observe Daylight Saving Time, don't forget to 'spring' your clocks ahead one hour this Saturday night! Official time change occurs at 2:00 a.m. local time on Sunday, March 13th.
Since 2007, daylight time has begun in North America on the second Sunday in March and ended on the first Sunday in November. On the second Sunday in March, clocks are set ahead one hour at 2:00 a.m. local standard time, which becomes 3:00 a.m. local daylight time. On the first Sunday in November, clocks are set back one hour at 2:00 a.m. local daylight time, which becomes 1:00 a.m. local standard time.
Not all places in the U.S. observe daylight time. In particular, Hawaii and most of Arizona do not use it. Indiana adopted its use beginning in 2006. In Canada, most of Saskatchewan, parts of Quebec, and Southampton Island in Nunavut do not observe daylight time.
Year Begin End
