The Time Change from Winter Time to Daylight Savings Time will take place in Latvia on March 31, 2019 at 3 in the morning. The clock jumps forward from 3 to 4 am. This means the people in Latvia have to cope with one hour less of sleep. As another consequence it is going to be darker in the morning again.
