How to format dates in next-intl?

next-intl provides comprehensive date formatting that automatically adapts to the user's locale. You have two primary approaches depending on your use case: formatting standalone dates (like timestamps or labels) using the useFormatter hook, or embedding dates within translated messages using ICU syntax. The library is built on the native Intl.DateTimeFormat API and supports all standard options, ensuring consistent formatting across both client and server components.

For dates that are not part of a larger translated message (e.g., a timestamp in a UI widget), use the useFormatter hook. This hook returns a format object containing a dateTime method. The method accepts a Date object and formatting options that follow the standard Intl.DateTimeFormat API.

For dates that appear inside a larger sentence or phrase (e.g., "Ordered on {date}"), you should embed the date formatting directly in your translation message. This keeps all text for a sentence together, which is much easier for translators. Use the ICU syntax with the date keyword.

next-intl also provides relativeTime for formatting dates relative to the current moment (e.g., "2 hours ago", "in 3 days"). This is available through the same useFormatter hook.

When formatting dates in Server Components, note that getFormatter is an asynchronous function and must be awaited. Forgetting await will result in a "is not a function" error.
