For over four decades, On Kawara (b. 1933, Japan) has created paintings, drawings, books, and recordings that examine chronological time and its function as a measure of human existence. The artist began making his now signature date paintings (known as the Today series) on January 4, 1966 in New York City, and continues to make them in different parts of the world. His practice is characterized by its meditative approach to concepts of time, space, and consciousness.
