Daylight is lengthening quickly this week. The sun rises on Baltimore at 7 a.m. today, nearly a half-hour earlier than the latest sunrise, on Jan. 5. At this clip, the sunrise would occur at 6 a.m. by March 27. But daylight-saving time starts March 9, shifting an hour of morning daylight to the evening. That flips our sunrise back to 7:27 a.m. - where it stood Jan. 5. But our gains are accelerating. We'll regain all this morning sunshine by April 16.
