National Novel Writing Month, also known by the acronym NaNoWriMo, is a creative writing challenge that happens every November 1 – 30.

What Is NaNoWriMo?
National Novel Writing Month began in 1999 as a daunting but straightforward challenge: to write 50,000 words of a novel in thirty days. Now, each year on November 1, hundreds of thousands of people around the world begin to write, determined to end the month with 50,000 words of a brand new novel. They enter the month as elementary school teachers, mechanics, or stay-at-home parents. They leave novelists.
NaNoWriMo officially became a nonprofit organization in 2006, and our programs support writing fluency and education. Our website hosts more than a million writers, serving as a social network with author profiles, personal project libraries, and writing buddies. NaNoWriMo tracks words for writers like Fitbit tracks steps, and hosts real-world writing events in cities from Mexico City, to Seoul, to Milwaukee with the help of 900+ volunteers in thousands of partnering libraries and community centers like… well, like nothing else.
NaNoWriMo is internet-famous. It’s community-powered (hello, Wrimos!). It’s hosted authors drafting novels like Water for Elephants, WOOL, and Fangirl. It’s a teaching tool and curriculum taught in 5,920 classrooms, and NaNoWriMo’s programs run year-round.
Whatever you thought NaNoWriMo is, it’s more than that.
