From the cited piece in the OP.
Bill Clinton is scheduled to visit Logan and Charleston on Sunday April 30, 2016. Hillary Clinton is scheduled to visit Williamson, WV on Monday May 01, 2016. More campaign stops are scheduled in West Virginia, but the details have still not been released.
What calendar do they use in West Virginia? Or is that detail still not released? Or were those dates supplied by the Democrats? Is this some kind of Weeklight Savings Time?
Inquiring horologists want to know.
