In Germany, we talk about ‘Brückentage’ or ‘bridge days’. According to Wikipedia, these are the days that are taken off from work to fill the gap between a holiday on Thursday or on Tuesday and the weekend. Ascension Day and Corpus Christi are always on Thursdays and so a lot of people take the Fridays off to have long weekends. We don’t have a name for these days in English. We just talk about having ‘long weekends’ as far as I know.
