how long was the government shutdown in 2018

The 2018 government shutdown lasted for 35 days, from December 22, 2018, to January 25, 2019. It was the longest government shutdown in U.S. history. The shutdown happened due to a funding impasse over President Trump's demand for $5.7 billion for a U.S.-Mexico border wall, which led to a partial shutdown affecting about one-fourth of government activities and furloughing around 800,000 federal employees. The shutdown caused significant economic impact and disruption to federal services.
