Wednesday is the last day in Baltimore with more daylight hours than nighttime until spring.
There will be about 12 hours, 1 minute of daylight, with sunrise at about 6:57 a.m. and sunset at 6:58 p.m. But the hours of daylight are shrinking by about 2 1/2 minutes each day.
Thursday, there will be about 11 hours, 59 minutes of daylight, meaning darkness will make up a slight majority of the day. This didn't occur on the day of the autumnal equinox, on Sunday, because Baltimore is so far north of the equator.
The "day" keeps shrinking until the winter solstice Dec. 21, when the sun will be up for 9 hours, 24 minutes, the "shortest day of the year".
Daylight hours will not surpass half the day until St. Patrick's Day next year. There will be about 12 hours, 1 minute of daylight on March 17 of next year.
