The official currency of Finland is the Euro (EUR), which has been in use since 2002. One euro is divided into 100 cents. The banknotes used in Finland come in denominations of 5, 10, 20, 50, 100, 200, and 500 euros, while coins come in denominations of 1, 2, 5, 10, 20, and 50 cents, as well as 1 and 2 euro coins. In Finland, it's relatively easy to find ATMs and banks in most urban areas. Most major credit cards, including Visa, MasterCard, and American Express, are widely accepted in hotels, restaurants, and shops. Some smaller establishments may not accept credit cards, so it's always advisable to carry some cash with you.

The official languages of Finland are Finnish and Swedish. Finnish is the more widely spoken language, with about 90% of the population speaking it as their first language. Swedish is spoken mainly along the coast and in the southwest of the country and is the mother tongue of about 5% of the population. The remaining 5% speak other languages, including Russian, English, and Estonian. Finnish is a Uralic language and shares similarities with Estonian, Hungarian, and Sami. It has 15 cases, which means that the endings of nouns, pronouns, adjectives, and verbs change to show their grammatical function in a sentence. Finnish is a phonetic language, which means that words are pronounced as they are written, making it relatively easy to read and write.

Finland's weather is influenced by its northern latitude, proximity to the sea, and continental climate. Generally, the climate is characterized by long, cold winters and short, mild summers. In the winter, temperatures can drop well below freezing, with average temperatures ranging between -6°C and -20°C (21°F and -4°F). The northern parts of the country may experience even lower temperatures, with Lapland being the coldest region. Snow is common in most parts of the country, and in Lapland, it usually lasts from November to May.

The power plugs and sockets used in Finland are Type F plugs, which are also known as Schuko plugs. These plugs have two round pins with a grounding pin at the bottom. The standard voltage in Finland is 230 volts, and the frequency is 50 Hz. If you are traveling to Finland from a country that uses a different type of plug, you will need to bring an adapter to ensure that your electronic devices can be plugged into the sockets. Some common types of plugs used in other countries include Type A, Type B, and Type C plugs. You can easily purchase a universal adapter that will work with different types of plugs and sockets.

As of 2021, the estimated population of Finland is around 5.5 million people. Finland is a relatively sparsely populated country, with a population density of only 18.2 people per square kilometer. The majority of the population (around 85%) lives in urban areas, with the largest cities being Helsinki, Espoo, Tampere, Vantaa, and Turku. Helsinki, the capital and largest city, has a population of over 650,000 people.

A fun fact about Lapland in Finland is that it is known as the "land of the midnight sun" during the summer months. This is because the sun remains visible for 24 hours a day in some parts of Lapland, due to the region's location above the Arctic Circle. This phenomenon is caused by the tilt of the Earth's axis and occurs between late May and mid-July each year. Visitors to Lapland during this time can experience the unique beauty of the midnight sun, where the sun never fully sets and the sky remains light and bright throughout the night.
