Fun fact: Wikidata has now existed for the majority of Wikipedia’s lifetime. https://query.wikidata.org/embed.html#%23%20How%20long%20Wikipedia%20has%20existed%20without%20and%20with%20Wikidata%2C%20and%20the%20date%20where%20both%20were%20equal.%0ASELECT%20%3FwikipediaStart%20%3FwikidataStart%20%3FwikipediaWithoutWikidata%20%3FwikipediaWithWikidata%20%3FdateWhereDaysWithoutEqualsDaysWith%20WHERE%20%7B%0A%20%20wd%3AQ52%20wdt%3AP571%20%3FwikipediaStart.%0A%20%20wd%3AQ2013%20wdt%3AP571%20%3FwikidataStart.%0A%20%20BIND%28%3FwikidataStart%20-%20%3FwikipediaStart%20AS%20%3FwikipediaWithoutWikidata%29%0A%20%20BIND%28FLOOR%28NOW%28%29%20-%20%3FwikidataStart%29%20AS%20%3FwikipediaWithWikidata%29%0A%20%20BIND%28%3FwikidataStart%20%2B%20STRDT%28CONCAT%28%22P%22%2C%20xsd%3Astring%28xsd%3Ainteger%28%3FwikipediaWithoutWikidata%29%29%2C%20%22D%22%29%2C%20xsd%3Aduration%29%20AS%20%3FdateWhereDaysWithoutEqualsDaysWith%29%0A%7D

bonus fun fact: I had reminders for this in both my private and work calendars, both set to today with slightly different queries, presumably added independently ^^

the “rollover date” was actually on Monday, but I had it saved for today for some reason – I’m guessing that at some point the “inception” of the Wikipedia item was set to 13 January 2001 (when the domain was registered) rather than 15 January (when the first edit was made), because then the math checks out for today
