A website that was founded sometime in 2012.
Its database includes 243217 (?) celebrities (including some duplicates).
Sometime in December 2018, it started including tv shows, songs, etc. to its database.
One thing about famous birthdays is that they sometimes use the term "recordings" (exp. One of her/his/their most viewed YouTube/TikTok recordings is insert video title/caption, with over insert number of views) to refer to videos and "recording" (exp. insert genre music recording) for a song (as the word means a recorded broadcast or performance), instead of just "videos" and "song/single/track".
Its url is famousbirthdays.com.

A cheeky little so-and-so who pretends it his birthday (on multiple occasions) simply for personal gain and benefit
