The "Mind over Madness" event on Friday includes free yoga classes all day. Fifteen thousand people registered to roll out their yoga mats and join in.
President of Times Square Alliance and co-founder of the event Tim Tompkins says part of its appeal is finding stillness and calm in the middle of the city rush.
Across the pond in England police say more than 20,000 people gathered at the famed Stonehenge monument to celebrate the solstice Friday morning. Cloud cover prevented bright sunshine at dawn but a joyous spirit prevailed.
