Further, in many nations, when a lone holiday occurs on a Tuesday or a Thursday, the gap between that day and the weekend may also be designated as a holiday, or set to be a movable or floating holiday, or indeed work/school may be avoided by consensus unofficially. This is typically referred to by a phrase involving "bridge" in most languages.
Four-day bridge weekends are commonplace in non-English speaking countries, but there are only a couple of examples in English-speaking countries:
In the USA, the fourth Thursday of November is Thanksgiving; but the adjacent Friday is made into a non-working day at some businesses. In Melbourne, Australia, the Melbourne Cup holiday is held on a Tuesday, but many people modify their work arrangements to also have the Monday off.
In Sweden a day between a weekend and a bank holiday is called "Klämdag" (Squeeze Day) and a lot of Swedes try to take a vacation day to have a long weekend.
The term for a four-day weekend in some Spanish-speaking countries is puente ("bridge") or simply "fin de semana largo".
