- Lent, the Christian time of penitence before Easter
- For the town in France, see Randan, Puy-de-Dôme.
A randan is a boat rowed by three persons, stern and bow using a single oar each and the central person a pair of sculls. The word is of unknown origin, and can hardly be connected with a slang term for a row or spree, which is found as early as the beginning of the 18th century and is generally taken as a variation of random, haphazard.
Additionally in Scotland, the term out on the randan describes a night of drinking and/or socialing.
randan in Polish: Randan (łódź)
