No. We have experence and have seen this before. This is like a
doctor who treats every pain with a dose of drugs versus a doctor who
actually diagnoses the problem and looks for a long-term solution.

Would you also design a schema with a table for male employees and one
for female employees? That wouild be splitting the entit on the gender
attribute. The holidays and non-holidays are still days. The holiday
attribute can change by decree or by definition (Easter, Chinese New
Years or other lunar-solar calendar holidays). Nobody can stop time or
skip a day.
As a simple test, when you have a printed calendar, do you put the
holidays on the pages of the calendar or on a separate piece of paper
on the other side fo the room? Can a holiday exist without a date
(ii.e. Can I put Christmas in a bottle by itself and pull it out as
needed)?
