Dates are formatted 1YYYY-MM-DD, i.e. the [ISO 8601](https://no.wikipedia.org/wiki/ISO_8601) standard (YYYY-MM-DD) plus 10,000 years. Thus they follow the [[Holocene calendar]], as introduced by [Cesare Emiliani](https://en.wikipedia.org/wiki/Cesare_Emiliani) and [advocated by Kurzgesagt](https://www.youtube.com/watch?v=czgOWmtGVGs). Years are written (e.g.) 12,024 in English contexts, and 12 024 in Norwegian contexts.
