2013 United States federal government shutdown
From October 1 to 17, 2013, the United States federal government entered a shutdown and curtailed most routine operations because neither legislation appropriating funds for the fiscal year 2014 nor a continuing resolution for the interim authorization of appropriations for fiscal year 2014 was enacted in time. Regular government operations resumed October 17 after an interim appropriations bill was signed into law.
