From January 4, 1966, Kawara made a long series of "Date paintings" (the "Today" series), which consist entirely of the date on which the painting was executed in simple white lettering set against a solid background. The date is always documented in the language and grammatical conventions of the country in which the painting is executed (i.e., “26. ÁG. 1995,” from Reykjavik, Iceland, or “13 JUIN 2006,” from Monte Carlo); Esperanto is used when the first language of a given country does not use the Roman alphabet (“6 AŬG. 1993”, from Tokyo).
