Government shutdowns in the U.S. have varied widely in duration, from just a few hours or days to more than a month. The longest shutdown lasted 35 days during the Trump administration from December 22, 2018, to January 25, 2019. Other shutdowns in recent decades have ranged from a single day to several weeks, with notable examples including a 21-day shutdown in 1995-1996 under President Clinton and a 17-day shutdown in 2013 under President Obama. Most shutdowns since 1980 have been relatively brief, typically lasting just a few days. The duration depends on how quickly Congress and the President can reach a funding agreement to resume government operations.
