“TH” most often stands for “Thursday” in casual calendars and chat, yet its meaning shifts with context.
From chemistry tables to gaming slang, the two-letter pair is small but loaded with significance.
Common Everyday Meanings of TH
When you spot “TH” on a planner, it almost always means Thursday.
Text threads and sticky notes rely on this compact abbreviation to save space.

Coders match the tag to standardized treatment categories.
Engineering and Technical Drawings
Engineers label threaded holes as “TH” on blueprints to avoid spelling the phrase each time.
The mark appears beside diameter callouts so machinists know to tap threads.
Missing the “TH” label can lead to costly re-work if holes remain smooth.
Mechanical Symbols
CAD software lets designers type “TH Ø8” to specify an 8-millimeter threaded hole.
The symbol streamlines documentation across global teams.
Electrical Schematics

This keeps schematics uncluttered while conveying vital safety info.
Finance and Ticker Symbols
Stock watchers occasionally see “TH” as part of a ticker suffix for preferred shares.
