The days were in the hymnal, but to be honest until about three years ago if they didn't fall on a Sunday very little mention of it was made. Now it is in the bulletin, and often mentioned in the sermon (depending on the pastor).
There is a greater awareness today than before. Before, as one pastor said, "They suffered under benign neglect".
And Kolo, we don't ask for their intercession. We only ask Jesus for that. The lives of the saints are to be used as examples of the faith.
