New Year's Eve is just four days away. And right now, workers in Manhattan's Times Square are busy getting ready for the annual big ball drop.

It's a tradition that started back in 1907. The first Times Square ball weighed 400 pounds and was covered in 100 light bulbs.

This year, around 288 water crystals have been mounted to the world-famous ball.

The huge sphere will be covered with more than 3,000 crystal triangles and weighs in at nearly 12,000 pounds.

Whether it's in person or on television, the descent of the Times Square ball draws in people from all around the world.

This year's theme is "Let there be friendship."

Times Square Alliance President Tim Thompkins said "New Year's Eve is about looking forward...[with a]…sense of hope and promise of change."

More than one million people are expected to hit the streets of New York City to ring in the New Year at Times Square.
