# Ad Orientem

> The worldwide directory of the Traditional Latin Mass: verified Mass
> locations and schedules, the traditional liturgical calendar, and vetted
> Catholic creators and educational content.

Ad Orientem exists to answer one question reliably: where and when is the
Traditional Latin Mass offered. Every location carries a verification state
and its sources; nothing is presented as confirmed that has not been checked
against an official or firsthand source.
