180dagers

180dagers is a term that appears in Dutch-language discussions to denote a set of initiatives, programs, or groups tied to a span of 180 days. There is no official definition or single canonical usage, and the term tends to be informal and regional rather than institutional. In practice, it is used as a shorthand to describe activities, commitments, or calendars that last roughly half a year.

Because usages vary, 180dagers can refer to educational or training cycles, residency or internship programs, or challenge formats promoted on social media. In some cases, organizers label a six‑month period as a "180dagers" track to signal duration and scope without prescribing a fixed curriculum. In others, it appears as part of discussions about migration, volunteering, or travel projects that span half a year.

Etymology is informal: the name combines the numeral 180 with a suffix imitating Dutch word formation; it is not a formal term in law, policy, or academia. Its meaning is therefore highly context-dependent and may differ between regions and communities.
