A New Year's Eve blue moon will be visible in the United States, Canada, Europe, South America and Africa (in Australia and Asia, the full moon does not show up until New Year's Day, making January a blue moon month for them). Blue moons happen every 2.5 years, but the last time one landed on New Years Eve was 1990.
The moon won't actually be blue, the term means it's a second full moon in one month. I'm not very superstitious, but I'm going to take this as a good omen for the new year, maybe even the whole decade.
