NEW YORK (CBSNewYork/AP) – It’s the first day of summer.

The Times Square Alliance is marking the occasion by offering sun salutations and other yoga moves at the crossroads of the world.

The 14th annual “Mind Over Madness Yoga” event takes place all day. There are different free yoga classes for people with different skill levels.

Summer begins at 6:34 p.m. on the East Coast. That’s when the Sun reaches its highest point in Earth’s sky.

Monday also marks the longest period of daylight of the year. The days will get shorter beginning Tuesday until Dec. 21, the winter solstice.

Sky watchers will later be treated to a rare full moon coinciding with the solstice. June’s full moon has traditionally been nicknamed the honey moon or the strawberry moon because of its large, reddish-amber appearance in the sky.
