The sound of a clock striking noon is one of the most reused time markers in video editing, long familiar from film, radio plays and cartoons signaling midday. Online, short isolated chimes like this became popular because they instantly communicate a time change without dialogue or on-screen text. Editors on YouTube, TikTok and in memes use the noon strike to jump forward hours, introduce lunch scenes, or reset the pace of a skit. Its continued use comes down to clarity: almost everyone recognizes twelve chimes as midday.
