SUMMARY:   China Invented the Work Week Around 100 BC (And It Started With Mandatory Bath Time) Around 100 BC, Chinese government officials were sent home every fifth day to take a bath. That bathing day became the foundation of what historians now believe to be the world's first formal work week.  Over the next 2,000 years, Imperial China built one of history's most elaborate leave systems, complete with festival holidays, wedding leave, sick leave, and a mourning policy so strict it nearly toppled a dynasty.

Summary

  • The Han Dynasty (200 BC - 220 AD) created the first structured work week: 4 days on, 1 day off for rest and bathing (Xiumu)
  • The Tang Dynasty (618-907 AD) shifted to 1 day off every 10 days but added extensive festival holidays and event-driven leave categories
  • The Song Dynasty (960-1279 AD) gave officials 113 days off per year (roughly one-third of the year)
  • Mourning leave (Ding You) required officials to resign for 2.5 years when a parent died, based on Confucian philosophy
  • The 1577 Zhang Juzheng scandal showed what happened when an emperor vetoed mourning leave for a powerful official
  • By the late Ming Dynasty, annual leave had been cut by 60% to about 50 days per year
  • China's leave model spread to Korea, Japan, and influenced practices across Asia
