when will the government shut down start

The US federal government shutdown is set to start at 12:01 a.m. on Wednesday, October 1, 2025, if Congress and President Donald Trump do not reach an agreement on a funding bill by the end of Tuesday, September 30, 2025. The shutdown will occur due to the failure to pass a spending bill to fund government operations beyond September 30. The last government shutdown was in late 2018, and this potential shutdown could lead to temporary suspension of some government services and furloughs of federal employees until a deal is made.
