In late October 2019, TikTok users began posting videos urging teens to skip school on December 2, tagged #2December. The trend spread within days, but no individual creator, organization, or reason for the date has ever been identified.
When skipping became a crime
Before the law required attendance, there was nothing to skip. Massachusetts passed the country's first compulsory-attendance law in 1852, requiring children aged 8 to 14 to attend school at least 12 weeks a year. Parents who refused faced a $20 fine.
Part of the point was to keep children out of full-time labor. The rule was as much about factories as it was about classrooms. It took another 66 years for the idea to reach every state, with Mississippi the last to require attendance, in 1918.
