My team works in the downtown office 3 days a week. Given Cassie's daycare pickup deadline and the Metra schedule, I leave at almost exactly the same time every day: 5:20pm. That makes the rapidly-lengthening days in late winter very noticeable.
Yesterday, for example, was the first day since November 2nd that my normal departure time was before sunset. And in just a couple of weeks—March 7th, most likely—I'll pick Cassie up from daycare before sunset.
It really makes a difference.
