Today, the people have the floor.
In Rome, not every day was made for politics. May 15 was a dies comitialis—a rare day when citizens could assemble, cast votes, and debate lawsuits or new laws in the open Forum. Magistrates didn’t just listen to speeches—they had to count every raised hand.
A calendar that ruled the republic.
The Roman calendar marked dies comitiales with a humble 'C'. On all other days—dies nefasti, fasti, or unlucky festival days—public business was off limits. For centuries, the republic ran on these tightly rationed pockets of democracy. The timing of power was a ritual all its own.
The Roman calendar strictly controlled when politics could happen. On a dies comitialis, every voice mattered—at least on paper.
