Pretty perpetual calendar giving the number of days for every month, along with the principal saints, the day when the sun enters the respective sign of the zodiac, the hours of daylight and night, and the hours of sunrise and sunset. A second disk at the bottom indicates the seven days of the week.
A little stained and rubbed; some repairs to the disks on the verso. The back cover bears a handwritten ownership by the seamstress Eleonore Rybak from Vienna's Ottakring district (ca. 1930) and a corresponding stamped label.
