I need the English word/phrase for a day between two holidays/days that people are generally not working – in my own language this is called "klämdag", so, for instance, if Thursday is a holiday, but the subsequent Friday isn't, then the Friday is a "klämdag". I have found some support for "bridge day" for this phenomenon, and it has been brought up here on Stack as well, but I can't find it in any of my dictionaries (Cambridge, Merriam-Webster, Longman). I realise from the other post here on Stack that the phenomenon as such doesn't exist in the UK or the US, so I guess that's why it isn't listed in any of my dictionaries.
My question now is: to what extent do native speakers of English nevertheless understand the word? Would most people understand it, or is it better to paraphrase?
