Time for Daylight Savings!

It is time to “spring forward” and set your clocks ahead one hour. Daylight saving time (DST) starts this Sunday, March 13, 2011 at 2:00 am.

Have you ever wondered why daylight saving time began?

The idea was first conceived by Benjamin Franklin as an effort to make better use of  daylight. The purpose of daylight savings time is to maximize daylight hours. The idea made a law in the United States in 1966, Uniform Time Act. This act does not require anyone observe it, but for those who do observe it, it’s uniform.

Beginning in 2007, daylight savings time was extended one month. It begins at 2:00 am on the second Sunday in March and ends at 2:00 am on the first Sunday of November. DST is not observed in Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands, and most of Arizona.

Other countries also observe DST. European countries observe daylight saving time from the last Sunday in March through the last Sunday of October. Russian clocks are set two hours ahead of standard time in the summer. During the winter months, Russia is one hour ahead of standard time. In the southern hemisphere, where summer comes in December, daylight savings time is observed from October to March. Tropical countries and those on the equator do not observe daylight saving time because their daylight hours are similar all year long.

I’m Dr. Randy LaFrom, a Cupertino and San Jose dentist, and I wanted to remind you to set your clocks forward this Sunday, March 13, 2011 at 2:00 am — especially if you’re scheduled for a checkup!
