New Year’s traditions vary hugely from country to country. But you can usually count on a few countdown constants, regardless of city — things like fireworks, rowdy crowds, possibly a local pop act (or 12). Millions of revelers have already said goodbye to 2013 tonight. Here’s how they’re ringing in 2014:

Taipei, Taiwan, celebrated with a six-hour concert and $1 million of fireworks launched from the city’s landmark skyscraper, Taipei 101. Per the Taipei Times, the theme of the extravaganza was Yuan Zai — the local zoo’s six-month-old panda cub.
