Interesting how the 1920s seem to be an era of social management experiments everywhere, with basic things like calendar being questioned all over the world. Just a few years later after Eastman's push for a reform in the United States, the Soviet Union actually changed its calendar. The reform affected the definition of a week rather than the month. The reform was not successful, and the changes were only in place in 1929–1931.

My grandfather, who turned 10 in 1929, vaguely recalled how the country briefly abandoned universal weekends, which meant a mess scheduling anything family-related. Everyone had different work schedules. https://en.wikipedia.org/wiki/Soviet_calendar
