The longest day of the year is one of the sweetest.
For the first day of summer Friday, which also is National Smoothie Day, several businesses are offering frozen freebies and discounts like 50% off smoothies.
June 21 also is National Selfie Day, Take Your Dog to Work Day, National Seashell Day and National Take Back the Lunch Break Day, according to NationalDayCalendar.com.
The freebie fest continues Saturday at Krispy Kreme.
Because 1 million free doughnuts were given out June 7 for National Doughnut Day, Krispy Kreme has a second deal. The doughnut chain is giving out its new Original Filled doughnuts, available in vanilla and chocolate, while supplies last.
