ISO 8601 based interval module

**The zero-dependency core of [date-interceptors](https://github.com/AdaskoTheBeAsT/date-interceptors): walks a parsed JSON graph and replaces ISO 8601 date strings with native `Date` instances in place.**

Return UTC time in ISO 8601

Node/Js-module for parsing and making sense of ISO8601-durations

**Moment.js bindings for [date-interceptors](https://github.com/AdaskoTheBeAsT/date-interceptors): walk a parsed JSON payload and turn ISO 8601 strings into `Moment` and `moment.Duration` values, plus a schema-driven Moment backend for the typewriter runt

**Luxon bindings for [date-interceptors](https://github.com/AdaskoTheBeAsT/date-interceptors): walk a parsed JSON payload and turn ISO 8601 strings into `DateTime` and `Duration` values, plus a schema-driven Luxon backend for the typewriter runtime.**

A tiny (110B) utility to sort ISO 8601 Date strings

**The Day.js binding of [date-interceptors](https://github.com/AdaskoTheBeAsT/date-interceptors): hydrates ISO 8601 strings in JSON payloads into `Dayjs` and Day.js `Duration` values, and plugs Day.js into the typewriter runtime.**

Customizable Date Picker for React

Linter for MADR (Markdown Architectural Decision Records) — supports v2 bold-list and v3/v4 frontmatter. Validates filename pattern, required sections, status enum, ISO 8601 dates, numbering uniqueness/gaps, supersedes bidirectionality, and inter-ADR link

**The date-fns binding of [date-interceptors](https://github.com/AdaskoTheBeAsT/date-interceptors): hydrates ISO 8601 strings in JSON payloads into `Date` and date-fns `Duration` values, and plugs date-fns into the typewriter runtime.**

Format dates as ISO 8601

Full ISO 8601 compatible parser.

**js-joda bindings for [date-interceptors](https://github.com/AdaskoTheBeAsT/date-interceptors): walk a parsed JSON payload and turn ISO 8601 date-times into `ZonedDateTime` values, plus a schema-driven js-joda backend that covers every date kind with its

JS library to provide an immutable date object that represents an ISO-8601 date (year-month-day)

Type-safe duration handling in TypeScript. Parse ISO 8601 strings, perform arithmetic, compare durations, and convert between units. Accepts numbers, objects, or strings. Immutable, zero dependencies.
