On This Day: June 12 Was a Dies Fastus
June 12 in Rome: It’s a dies fastus—law courts are open, deals get struck, life moves forward until sundown.

A day for business, not superstition.
Not all Roman days were created equal. A dies fastus, like June 12, let magistrates hear cases and citizens conduct official business. No sacred taboos, no forced holidays—just the daily churn of a city obsessed with contracts and court dates.
Calendars controlled everything.
Priests marked days with mysterious letters, more code than calendar: F for fastus, N for nefastus. Start the wrong lawsuit on a forbidden date, and the gods might doom your case. For Romans, checking the calendar was as crucial as hiring a good lawyer.
The Roman calendar wasn’t just dates. It determined fates: who could sue, vote, or even get married. Power lived in the margins of the month.
