Novena means nine. That means nine straight whatever, days, months, years, hours, etc.
An approved novena sometimes has indulgences or promises attached, and those are not
guaranteed unless the time frame is met. If you miss one, start over. Your other prayers are not wasted.
St. Faustus made a novena of saying 1000 hail marys a day for nine days straight. She
did this only three times in her life. It would take about 3 1/2 hours to do this. But she did this along with her other duties and prayers each day. Now that’s a novena to end all novenas. Their were no indulgences as such for the novena. And you think you have it tough.
Just an extrodinary novena idea.
Ps. It would be ugly just to keep track of how many were said and when, and how many to go.
