I don't see charts here...

Except for 54 days the above quoted site is nothing like what North Americans and British have been praying for 100 years.

So this link to a French site looks like it requires the 15 decade Rosary everyday.
In French "Rosaire" is 15 decades, whereas "chapelet" is 5 decades.
Are there special beads for this Novena?

God bless+

This is the link that shows 5 decades per day.  The chart on the second page is the same as in the back of the English booklets, so certainly not 15 decades per day.


Also every decade is prayed for a particular virtue.
