work day and working day

[tedmc]

It is not a weekend or public holiday today. It is a ..... day.
What should the word be - work or working?
What is the difference between the two?

If the above was correct, there would be no difference.

I never heard of a working day before. Where is it called a working day?

In plenty of places, apparently. [link]
