While several events have been planned to celebrate Mother Teresa's 100th birthday across the globe, New York in United States will be the city decked the most with the colours of Missionaries of Charity.
The landmark Times Square will have marquees and hoardings up on Thursday, Aug 26 evening in white and blue. Named the Great White Way, bright neon lights will light up the city's celebrations.
