Spoken languages: Danish is the official language, but most Danes are fluent in English.
Local habits and customs: Denmark is a liberal, tolerant country. The Danish language doesn't have a specific word for “please”, so don't be upset if Danes leave it out when talking to you in English. Tipping is not expected, as service charges are included in hotel, restaurant and bar bills.
Currency: Denmark uses the Danish krone (DKK). Major credit and debit cards are widely accepted, but it's a good idea to carry some cash for smaller vendors.
Getting around: Denmark has a swift, easy-to-use public transport system. Danish State Railways runs an exhaustive, reliable rail network, with services ranging from the large intercity expresses (lyntog) to smaller local trains (regionaltog). Ticket prices are calculated according to a countrywide zonal system. The bus network is also extensive, although prices don't work out much cheaper than trains. Ferries or bridges link all of Denmark's principal islands, and where applicable, train and bus fares include the cost of crossings. Bicycles are a popular and practical way to get around, and many cities offer bike rental schemes.
Electricity and plug types: The standard is 230 volts with European-style two-pin plugs. UK travellers will need an adaptor.
Time zone: Denmark is on Central European Time, which is 1 hour ahead of GMT. Daylight Saving Time applies.
