## What This Chart Shows

Duration in days of every federal government funding gap and shutdown since 1976, when the modern budget process created by the Congressional Budget and Impoundment Control Act of 1974 first took effect.

The chart distinguishes between two eras:
- **Pre-Civiletti (1976–1980):** Technical funding gaps where agencies continued operating. Shown in a lighter color. These were not operational shutdowns — they are included for historical completeness and to show the contrast.
- **Post-Civiletti (1981–present):** Real operational shutdowns where agencies halted, workers were furloughed, and services were interrupted. Shown in the primary color.

## The Civiletti Distinction

The modern government shutdown was created by a legal opinion, not by Congress. Attorney General Benjamin Civiletti issued an opinion on April 25, 1980, asserting that any agency spending during a lapse in appropriations was a criminal violation of the Antideficiency Act. Before this opinion, agencies continued operating during funding gaps under the assumption that Congress would retroactively cover expenses. After this opinion, agencies were required to halt operations immediately upon a funding lapse.

This is why the pre-1980 entries in the chart are marked as non-real-shutdowns — they were technical lapses, not operational closures.

## Methodology Notes

- **Duration counting:** Chart uses calendar days of the active shutdown, consistent with standard media reporting. The CRS uses a slightly different methodology (full days of funding gap), which typically produces a count one day shorter. The difference is editorial, not substantive.
- **The 2025-26 entry:** The 76-day DHS partial shutdown ended during the preparation of this chart. It is included as a completed data point.
- **Multiple shutdowns in one fiscal year:** Several fiscal years had more than one shutdown (FY1978 had three). Each is shown as a separate bar.
- **Cost estimates:** Not all shutdowns have published cost estimates. Where estimates exist they are noted in data.csv. Costs are not shown in the chart to maintain visual simplicity.
