That list is not comprehensive — but even that may be more than Congress can hope to do, according to a number of Republicans in the Senate.

Why? Well, part of the problem is that, over the course of the month, both the House and the Senate are in session on only 12 days. For those keeping track at home, the month of September includes 21 weekdays. Meaning that on fewer than two-thirds of September weekdays, both chambers in the Capitol will be occupied.

On only 40 percent of the days this month will both chambers be in session. But, then, the average since 1979 is only 46 percent.

And September is a relatively good month historically, probably because it comes after the month of August, in which Congress rarely does anything. (On 82 percent of August days since 1979, neither chamber has been in session.)

That said, on an annual basis, 2017 is poised to have an unusually high number of days in which both chambers are in session: 38.1 percent of the year, both the House and Senate will be at work on Capitol Hill. That’s the highest percentage since 2011.

On about one of every two days this year, neither chamber will be in session. That includes 44 of the 92 days of the year from October through December. In other words, if you worked every weekday from Sept. 1 to Friday, Nov. 17, you’d have worked the same number of days as both chambers of Congress will be in session from Sept. 1 until 2018.
