when did the government shut down last

The last U.S. federal government shutdown occurred from December 22, 2018, to January 25, 2019, lasting 35 days. It was the longest government shutdown in U.S. history. This partial shutdown happened due to a funding impasse over President Donald Trump's demand for $5.7 billion to build a border wall with Mexico. During this period, about 800,000 federal employees were affected, with around 300,000 furloughed without pay. The shutdown ended when Congress passed a plan to reopen the government for three weeks to negotiate further funding.
