In one word, I say "depends".
It depends on a lot of factors like your goal, passion, enjoyment, mental exercise, etc.
First of all, we need to know, Why we play a particular game?
Is it for fun or to build a career or to exercise your brain or just to pass time?
If you are just a hobby player and need chess to play and defeat your friends, then it is okay to skip a day or two or even more.
For mental exercise, you can practice occasionally and also daily. But, don't overdo it.
If you are serious about becoming a professional player. It is highly recommended to practice chess daily,with a proper schedule ( preferably prepared by a professional).
Daily practice of any skill has many fruitful results like building a neural path, enhancing your experience of that skill, exponential growth in that skill, etc.
