In English Wikipedia, there are two different types of On This Day links:
- Today's info: https://en.wikipedia.org/wiki/Wikipedia:On_this_day/Today
- Any date (this is used to create the canonical on-this-day display: https://en.wikipedia.org/wiki/Wikipedia:Selected_anniversaries/August_31 and https://en.wikipedia.org/wiki/January_15
Questions coming from the deep linking On This Day (https://phabricator.wikimedia.org/T172759), which was quickly completed to use the functionality for widgets:
- We're currently swallowing the first link and bringing them to our On This Day view. Should we also swallow links of the second variety? (That page allows editing and such - which our On This Day view does not do.)
- "On This Day" is a different page URL in different languages. We're currently only swallowing links for English Wikipedia's On This Day URL format. Is there a canonical list of "On This Day" URLs so we can swallow all of them?
(Once these are answered, we should use this ticket - or a new one - to complete the work.)
