The Kosmos 1 biorhythm calculator is a four-function calculator with additional biorhythm calculation functions, which can calculate a person's present position in their three biorhythm cycles; physical, emotional, and intellectual. The calculator has an eight-digit vacuum fluorescent display (VFD) with a ninth digit for negative and error indication. It is powered by three AA batteries, or a power adapter.

The theory of biorhythms is that a person's daily life is affected by three rhythmic cycles: physical, emotional, and intellectual. Each area has a different cycle length; the physical cycle lasts 23 days, the emotional cycle lasts 28 days, and the intellectual cycle lasts 33 days. Each individuals biorhythm cycles are based on their date of birth, and oscillate in a steady (sine wave) fashion throughout life.

Charting biorhythms was popular in the United States in the 1970s. Places such as video and amusement arcades had machines that could calculate people's biorhythms based on their date of birth. Computer programs were available that could calculate people's charts, as well as calculators such as the Kosmos 1, and the Casio Biolator.

This 1977 Kosmos 1 Biorhythm calculator belonged to film editor Peter Boita, who purchased it in the late 1970s. Peter Boita worked as a professional film editor from the late 1940s until the late 1980s working on diverse films such as Carry On Sergeant, Swiss Family Robinson, The Far Pavillions, and Aliens. It was very kindly donated by his son Peter Boita Jnr.
