ICU plural rules playground: see how cardinal numbers resolve to plural categories (zero, one, two, few, many, other) for each locale, matching the logic behind ICU MessageFormat plural and selectordinal. Part of ICU Message Tools.

Open plural rules by locale for ICU template snippets, build messages in the online editor, validate JSON in the validator, or read MessageFormat examples.
