FormattedDate

Accepts a Date, Temporal.PlainDate, or ISO date string via date; renders inside a <time> by default (override with as, e.g. as={Fragment} to avoid the wrapper, useful inside <option>).

• locale="fi", date=ISO string: 5.8.2026
• locale="en", date=ISO string: 8/5/2026
• locale="fi", date=Temporal.PlainDate: 5.8.2026
• locale="fi", date=Date (interpreted in timezone, default Europe/Helsinki): 5.8.2026
• locale="fi", date=null (renders nothing):
• as={Fragment} (no <time> wrapper): "5.8.2026"

Calling formatDate() directly (requires a Temporal.PlainDate): 5.8.2026
