What day is it in the Roman calendar? Tempora Romae shows you.

See today's date as the Romans wrote it, with Kalendae, Nonae, and Idus. Browse a full monthly calendar in authentic Roman format, complete with day names in Latin.

The app uses your location to calculate temporal hours: the variable length hours the Romans actually used, divided equally between sunrise and sunset. Watch them tick on a sundial visualisation.
