Kawara began making his date pictures, known collectively as the “Today” series, on 4 January 1966 in New York and continued to work on them for the rest of his life. Each hand-painted work was completed on the date depicted and most were packaged with newspaper clippings from local publications. Because Kawara refused all interview opportunities and declined even to have his photograph taken, the thousands of pictures made in the series cultivated an air of mystery, despite their deliberate tedium. Kawara felt they should speak for themselves.
