Calendar Versioning (CalVer)

Calendar Versioning (CalVer) ties version identifiers to release dates rather than semantic compatibility signals. Common formats include YYYY.MM.DD, YYYY.MM, or YYYY.0N. CalVer communicates when a release occurred, which is useful for time-sensitive software, but provides no inherent MAJOR/MINOR/PATCH compatibility signal — document breaking changes explicitly.

Formula: Scheme-specific; often YEAR.SEQUENCE or YY.MINOR.MICRO — compatibility is by policy, not the number alone.
