How long is the longest day of the year? 25? 26? or 27 hours? Wait….that’s not what “longest day” means? It’s a sun-believable ☀️ day to #GetOutside because today has more hours of sunlight than any other day of the year! Happy #SummerSolstice! 😎 #LongestDay #Sunlight #Sun 📸: NationalParkService Image: Six visitors sit around a fire at sunset
