If you plan on celebrating Father's Day by soaking up as much sun as possible, this would be the year to pull it off. Summer Solstice marks the official start of summer and this year it falls on June 21. From a scientific standpoint, the sun will be at its highest point in the sky if you live in the northern hemisphere.
But you probably know it better as that day with the most daylight. It also coincides with Father's Day in 2015, so really, your excuses to celebrate your old man with a family BBQ outside are looking pretty slim right now. But if you're lacking for inspiration on how to celebrate the first day of summer, look to Europe.
England's Stonehenge will be party central for "caped druids, antler-wearing poets, and ragged mummers", according to National Geographic. It's one of the rare moments people are allowed to stand within the inner circle of the monument.
Head farther north to select Scandinavian countries and you'll also have plenty of options on how to celebrate with all that extra daylight.
Sweden and Finland welcome June 21 with their Midsummer's Eve celebration. Many locals deck their houses out with flowers along with a maypole, which celebrants dance and sing around, though these rituals are more tied to pre-Christian rituals and less about the longest day of the year.
So jot June 21 down on your calendars because it's The One Thing You Should Know Today.
