The start of Daylight Saving Time begins at 2 a.m. on Sunday, March 13. Here's seven fun facts about daylight saving time:


Studies: Less violent crimes

A number of studies have shown that crime is consistently less during daylight saving time. Light evenings seem to make crimes, like mugging, less appealing to criminals.


Arizona is on standard time

In the United States, Arizona (with the exception of the Navajo Nation) and Hawaii do not observe daylight saving time. Because, really, do they need more sunlight?


Indiana joins DST in 2005

Until April 2005, Indiana had its own complex way of telling time. The state was spilt between two time zones and only some of the counties observed daylight saving time.

Extra Light

Lobbyists for time change

Organizations and businesses that lobby for keeping daylight saving time include the Chamber of Commerce, golf courses, gas stations, and grill and charcoal industry leaders.


But we save energy, right?

If we have more light, we're less likely to turn one on — at least that's the argument. But studies show the energy savings to be minimal. Most families use more gas during DST.


What about the farmers?

Most of us were told DST was invented for the farmers. But farmers were one of the strongest lobbyists against it. Dairy farmers argue that cows' milking schedules don't adapt.

Sleep Pattern

Change affects health

Research published in the New England Journal of Medicine showed that in Sweden, heart-attack risk rose after the time change. Disturbed sleep was a possible explanation.
