I18n Date Patterns

This is a reference skill for building multilingual React apps with react-i18next and dayjs. It enforces patterns like useTranslation for all UI strings, useFormatting for currency and lists, and ICU MessageFormat for plurals. The anti-patterns section is the real value here: it explicitly forbids things like hardcoding strings, using .join() for lists, or new Date() for formatting. Comes with bundled references for the formatting hook API and Trans component examples. If you're working on a codebase that supports Hebrew or Arabic, the RTL guidance and logical properties approach will save you time. Low effort skill that acts as a guardrail.
