On March 19 in 1918, Congress approved daylight-saving time"
"The date and time of all clock changes is determined by the week number in March or November and always happens at 2:00 a.m. on a Sunday. Clocks "spring" forward on the second Sunday in March, and "fall" back on the first Sunday in November."
That's right. Daylight Savings Time was approved so one gets an extra hour of daylight in the evening.
Will you spend it on 10- and 15-meter openings to Asia?
In the mean time, don't forget to Spring Forward this weekend.
