More than 12,000 people - a microcosm of the world in a city of immigrants - participated in the 13-hour yoga marathon that started at 7.30 am.
India's Consul-General Riva Ganguly Das brought India's message of yoga at a noon-time ceremony marking the summer solstice in the northern hemisphere.
This was the 15th year the summer solstice was celebrated with yoga in Times Square, a practice that began long before the UN declared June 21 as International Day of Yoga in 2014.
The event is billed as "Solstice in Times Square: Mind over Madness".
This year its theme was "Ahimsa, Non-violence," according to Tim Tompkins, the President of Times Square Alliance which organises it.
Authorities are reluctant to call it a terrorist attack and attribute it to an American who was high on drugs.
Stretching across several city blocks along Broadway, New Yorkers and tourists performed 'asanas' in hour-long sessions with instructors from several yoga organisations and studios with colourful yoga mats spread on the street.
