You know how some people figuratively say "Ugh, it was a long day today!" because they do so much or it takes "longer" for them to finish stuff during a day... but it isn't the longest day? TODAY is the longest day and the only day they can say that and be right figuratively and literally. It also marks the beginning of SUMMER. The summer solstice will happen when the earth's axis is tilted most towards the sun. This year, it will be TODAY at 17:16 hours. Make the most out of the day with the most sun in the Northern Hemisphere! Happy Summer Solstice!
