Principally intended for use on user pages, but can also be of some use on Wikipedia-namespace (policy, project, etc.) and portal pages. Not intended for use on articles.

To suppress the "Last update:" text, use |dateonly=yes:

• {{Last updated|dateonly=yes}}

renders as:

• 2023-06-23

To link the date so that it autoformats (e.g. into International or US instead of Unix-style dates) for users with date preferences set, use |format=yes. Note that if the template is substituted, bots may remove this linking, per WP:MOSUNLINKDATES.:

• {{Last updated|format=yes}}

renders as:

• Last updated: 2023-06-23
