OK you summer sun worshipers, your day has arrived. Today marks the official arrival of summer. It’s officially called the Summer Solstice in the Northern Hemisphere and it arrives officially at 11:24 p.m. central time. It is the day when the sun is the furthest to the north that it will get which also means that today we will have the longest amount of daylight as well. The daylight time will get shorter each day beginning tomorrow.
