20år

20 år is a Swedish term used to denote twenty years, either as a duration or as age. In Swedish, compounds like 20-årig and 20-årsjubileum are formed; 20-åring means a person who is twenty years old.

As a time span, 20 years is two decades. It is used in planning and finance (such as long-term mortgages or forecasts) and in historical or demographic contexts. A 20-year period comprises about 240 calendar months and roughly 7,300 days, accounting for leap years.

As age, a 20-year-old is considered a young adult in many societies. Rights and responsibilities related to age vary by country and jurisdiction; in many places the most common thresholds for various activities sit at 18 or 21, making 20 a transitional age rather than a universal legal milestone.

In culture, the phrase appears in expressions such as 20-årsjubileum (a 20-year anniversary) and is used in media to denote a period of two decades. The concept is tied to the Swedish language, with equivalents in other languages—such as “two decades” in English—reflecting a common way to express a long but finite span of time.
