The provided texts function as a comprehensive listing of celebrity birthdays throughout the month of January. The first source, titled "Celebrity Birthdays: January 1–4," specifically covers the first four days of the month, starting with Jane Doe and ending with Matt Frewer. The second, much longer source, titled "Pasted Text," continues this catalog by providing names for every subsequent day, from Suki Waterhouse on the 5th through Justin Timberlake on the 31st. Notably, the compilation occasionally includes brief, parenthetical details or cultural references to help identify certain individuals, such as YouTuber Ruby Rube or influencer IShowSpeed. Together, these two documents present a complete calendar of notable January birth dates.
