Template:On this day/doc

Usage
Place on an article's talk page to produce the following message:

If the page has been featured on multiple dates, use additional date# and oldid# parameters:

Dates should be entered in YYYY-MM-DD format; they are reformatted appropriately for display.

The template is automatically added or updated by AnomieBOT at the end of each day - there is no need to add it manually.
