30jaars

30jaars is a Dutch term used as a shorthand to indicate a period of thirty years or, less commonly, an object or event tied to that duration. In contemporary Dutch, the hyphenated form 30-jaars is the usual way to write the modifier when referring to a duration or a jubileum, for example in phrases like 30-jaars jubileum or 30-jaars garantie. The non-hyphenated plural form 30jaars appears mainly in headlines, lists, or informal contexts, but is far less common in formal prose.

The meaning of 30jaars depends on context. It can denote a time span of thirty years, as in a 30-jaars periode, or function as part of a compound describing a milestone, such as a 30-jaars jubileum marking the anniversary of an organization, project, or product. When describing people, standard Dutch would use dertigjarigen for thirty-year-olds or dertigjarige for something related to the age of thirty, rather than 30jaars.

Orthography varies with style guides and media practices. In formal writing, spelling out numbers or using standard forms like dertig jaar or dertigjarige is often preferred, whereas 30-jaars is common in marketing, contracts, or media shorthand where space or brevity is a priority.

Related terms include dertig jaar (thirty years), dertigjarig/dertigjarige (thirty-year-old or thirty-year period), and jubileum (anniversary). The use of 30jaars reflects Dutch practices for creating compact compound modifiers around numerals and the noun jaar.
