A People's Calendar (aPC) is a project that seeks to promote the worldwide history of working class movements and liberation struggles in the form of a searchable "On This Day" calendar.

aPC was inspired by historian Howard Zinn's work "A People's History of the United States". Zinn's scholarship and political activism demonstrated the power of mass working class movements, as well as the critical importance of knowing this history when we seek to change the present.

The greatest experts on any historical event or struggle will always be the people who live it, as well as the scholars who document it meticulously. Our ambition is to promote awareness of this history while emphasizing these perspectives.

Event anniversaries are posted daily on social media! You can follow us on Facebook, Instagram, Threads, and Reddit.
