A date, time, or duration with a machine-readable datetime attribute.
Baseline: Widely available · Inline text semantics
When to use it
For every date and duration on a page — search engines read the datetime (2026-07-24, PT45M) while humans read the prose.
When not to
Don't skip the datetime when the content isn't already machine-parseable, and don't use it for vague times ('the olden days').
