Today at 02:00:00 AM clocks are turned forward 1 hour to Sunday, March 25, 2018, 03:00:00 AM local daylight time instead.
As a result, sunrise and sunset will be about 1 hour later on Mar 25, 2018 than the day before. There will be more light in the evening.
This is also referred to as 'Spring Forward', 'Summer Time' and 'Daylight Savings Time (DST)'.
(The clocks go backward again on October 28 2018)
