HolyDB
Find Catholic churches nearby with Mass, Confession and Adoration times.
Connects to a database of US Catholic parishes built from parish websites. Muse can find churches near a location or by name, show weekly Mass, confession and adoration schedules, and filter by day or time window. Regular weekly times only, so parish websites should be checked for holy days and changes.
Try asking Muse: "Find a Catholic church near me with confession on Saturday afternoon."
