I used to work with someone who had a message telling people she only checked her email twice a day. You pretty much needed to call her if you needed anything outside of those times. (She worked in a remote office.) I think she had read one of those books on efficiency that recommended scheduled email time. But there were problems with this: 4. My department often had to email attachments or text to illustrate our questions/concerns. And we were on deadlines. Reading a page of text over the phone was not an efficient use of anyone’s time 5. She did outreach & was often out of the office on site visits, trainings, or travel to these places, but never ever set her OOO for these, because she was “working.” However, she was effectively not available to read emails from other staff until after hours on those days.
One of the most important things to do when leaving office is to create an out of office auto-reply email. It’s a must for you to let your business associates and colleagues know how and when they will be able to reach you again. You should do that even if you are planning on just resting at home — it shows a certain level of professionalism.

Literally just “Please note that (date) is a public holiday in (country). I will not be checking my inbox until (next working day).”
