The astronomical calendar first came out in 1953, and were meant to be "helpful tools for those many educational establishments where astronomy, cartography, and geodesy are taught." The calendar's introduction expresses the hope that "it will interest the working people of our republic." That came to pass - the 1990 version of the calendar had a print run of 15,000. The astronomers of the University of Latvia participated in the creation of the calendar. It was printed as a standalone publication until 2000, after which it was printed as an addendum to the popular science magazine "Zvaigžnotā Debess" or "Starry Sky."
