Direct answer: The 2025 U.S. federal government shutdown lasted 43 days. Context and details:

• It began on October 1, 2025, when funding expired and the government partially shut down after Congress failed to pass appropriations for the new fiscal year.

• The shutdown ended on November 12–13, 2025, after Congress and the President approved and signed a funding package, reopening most operations. Reuters/BBC reports confirm the 43-day duration and the late-November signing that effectively ended the shutdown.

• This event set a record for the longest shutdown in U.S. history, surpassing prior 2018–2019 shutdowns, which lasted 35 days.

If you’d like, I can summarize key impacts (furloughs, pay delays, affected agencies) or provide dates for major milestones during the shutdown.
