How Many Days Does Congress Work?

2026 is not over, so its number is a running total and will keep rising until the second session of the 119th Congress adjourns. It is not comparable with the completed years below, and nothing on this page averages it in.

The question usually arrives with an assumption attached. The record does not support it: averaged by decade, session days per year have risen since the 1990s.

These figures count days on which at least one chamber was in session, measured by publication of the daily Congressional Record — the official record of proceedings, published for each day Congress sits.

That is deliberately not the same as the per-chamber figure. The House Clerk and the Senate each publish their own “days in session” counts, and both are lower than the number here, because the chambers do not sit on identical days. For 2024 this measure gives 196 days, while the House and Senate separately reported figures in the low-100s and high-160s. All three numbers are correct; they answer different questions. If you need one chamber specifically, use that chamber’s own calendar.

A pro forma session — a sitting held to satisfy the constitutional bar on adjourning for more than three days, sometimes lasting seconds — counts as a session day here, because it counts as one in the record.

Coverage begins in 1995, which is where Congress.gov’s daily Congressional Record collection starts. Earlier Congresses are not missing; they are outside the source.
