Has anyone researched a possibly significant increase in births on Labor Day?
You mean because people might go into labor on labor day? 
This forum is intended for comments on Straight Dope columns. I cannot find the relevant column to your posting. Please let me know to which column you are referring. If there is no column related to your question, I will move this thread to the General Questions forum.
Unless you were making a sly reference to the column «Does May Day actually commemorate the birth of the Illuminati? (04-Feb-1982)»

Welcome to the Straight Dope, and thank you for posting your comment.
Since the article is not related to a Straight Dope column, this thread is leaving the Comments on Cecil’s Columns forum and going to visit my colleagues Eutychus55 and UncleBeer in the MPSIMS forum.
