The claim is mostly true because a government shutdown occurs when Congress fails to pass funding legislation on time, causing the federal government to cease non-essential operations, though essential services continue functioning.

What the Evidence Shows
A government shutdown happens when Congress does not pass the necessary appropriations bills or continuing resolutions to fund federal government activities by the deadline. This failure triggers a cessation of federal operations that are considered non-essential or discretionary until new funding legislation is enacted. Essential services and mandatory spending programs, such as Social Security and national security functions, continue to operate despite the shutdown.
Multiple sources confirm that the shutdown results from the inability to pass funding bills on time, leading to a partial halt in government operations rather than a complete cessation. The claim's wording that the government "ceases its operations" is somewhat imprecise because it does not distinguish between essential and non-essential functions, which is an important nuance.
