When should I start?
A novena lasts nine days. To have the ninth day fall on a feast, start eight days before. This free tool uses the feast days as given in Bonaventure Hammer’s 1909 book, which is in the public domain. You may also start on any other day. US$0 / KSh 0.
For 2026, the Immaculate Conception novena may be started on 30 November, so that the ninth day is the feast, 8 December 2026.
The Android app, Novena Companion, has the full prayers in large type, offline, with a Tagalog interface. About the app. Google Play — coming soon.
