In Washington, D.C., on Capitol Hill, there are clocks everywhere. Every Congressional office suite, according to the Architect of the Capitol, has at least three clocks in it. There are around 4,000 clocks on the House side of the Hill, and just slightly less on the Senate side. There are fancy, old clocks, that need to be regularly wound; there are newer, decorative clocks that adorn the mantlepieces of legislators’ personal offices; and there are practical wall clocks, with wide white faces, that look a lot likethe clocks in elementary school hallways and classrooms.
These thousands of clocks, though, don’t just tell the time. They’re part of system more than a century old that sends signals, in a code of sounds and lights, to members of the House and Senate.
Look along the top of a Congressional wall clock, and you’ll see seven small light bulbs. Even the fancier clocks in members’ offices have them. From time to time, these will light up in particular sequences, accompanied by loud, long buzzes or series of shorter buzzes. These patterns all have meanings: they’re meant to communicate to people working on the Hill when electronic votes are called, when one chamber or the other is adjourned or in recess, and when members need to think about actually being in the Senate or House chamber.
