You are correct. However, note that there is a difference between public Holiday and National Days(Enshrined in the constitution) .

Costitution says;

(3) The national days are––
(a) Madaraka Day, to be observed on 1st June;
(b) Mashujaa Day, to be observed on 20th October; and
(c) Jamhuri Day, to be observed on 12th December.
(4) A national day shall be a public holiday.


Note Labour day, Just like Moi day are both public holidays unless ammended by parliarment.

This issue was exhaustively discussed exactly a year ago:
