The so-called "Chinese New Year" isn't only observed in China, a fact that my Korean mother would like to remind me when I got excited about dragon dancers in elementary school.
You know how people say that New Year's Eve is for amateurs? Mardi Gras is for professionals. Not that you need any special expertise to partake in the season (and yes, it's a seaso: Carnival season!), but rather than the one-night-and-it's-over sprint of New Year's Eve, Mardi Gras lasts for many weeks.
