March 10, 2013
The Time Change from Winter Time to Daylight Savings Time will take place in the USA on March 10, 2013 at 2 in the morning. The clock jumps forward from 2 to 3 am. This means the people in the USA have to cope with one hour less of sleep. As another consequence it is going to be darker in the morning again.
