Sunrise, Sunset

Today is the first full day of summer, since the solstice occurred yesterday morning, shortly before noon local.

Days are getting shorter from this point. According to Weather Underground, tomorrow will have four seconds less daylight than today.

Paradoxically, however, the sun will set ten seconds later tomorrow than it did today. In fact, sunset will continue getting later in the evening. Here at roughly 40ยบ North latitude, the latest sunset happens about a week from now in late June. The days are shortening, but they are shortening for now because sunrise is starting to happen a few seconds later each day.

The days don't really start contracting noticeably from both ends until early July.
