In 1975, a calendar made by the Kaunas P. Zibert's Red Flag Order Silk Factory went into space. It spent 62 days, 23 hours, 20 minutes, 8 seconds on the space station Salyut-4 with cosmonauts P. Klimuk and V. Sevastyanov. This calendar was later sent to the editorial board of the Izvestia newspaper. The workers of P. Zibert's factory were very proud. The factory, established in 1951, operated till 1990.
An action plan is something that helps people to avoid making mistakes in daily life. Work calendars help to plan their actions. The instructions and descriptions of actions help to complete their work accurately.
