Are we sure Groundhog Day was made to abolish Catholic Holidays? This is what Wiki says about the history.
“Historical origins
The groundhog (Marmota monax) is a rodent of the family Sciuridae, belonging to the group of large ground squirrels.
Perhaps the earliest known American reference to Groundhog Day can be found at the Historical Society of Berks County in Reading, Pennsylvania. The reference was made February 4, 1841 in Morgantown, Berks County, Pennsylvania storekeeper James Morris’ diary: “Last Tuesday, the 2nd, was Candlemas day, the day on which, according to the Germans,[5] the Groundhog peeps out of his winter quarters and if he sees his shadow he pops back for another six weeks nap, but if the day be cloudy he remains out, as the weather is to be moderate.” (Legend has it that the groundhog is a timid creature, and the sight of his own shadow will scare him.[1])”
They are talking about Candlemas here. I would like to see Mark Shea’s reference on this.
