ccw

CCW is an acronym that can refer to several different terms depending on the context. In mathematics, physics, and related fields, CCW stands for counterclockwise, indicating a rotation or orientation opposite to the direction of a clock’s hands. This convention appears in angular measurements, vector cross products (often described using the right-hand rule), polar coordinates, and computer graphics. Some style guides prefer counter-clockwise or anti-clockwise, but CCW is widely understood in technical writing.

In the United States, CCW commonly denotes a concealed carry weapon permit or license. A CCW license authorizes the holder to carry a concealed firearm in public, and the rules vary by jurisdiction. Requirements typically include age limits, background checks, and firearms training. Restrictions may apply to certain locations, such as schools, government buildings, or bars, and many states maintain reciprocity agreements recognizing other states’ permits. Because laws change and vary widely, individuals are advised to consult local authorities for up-to-date guidance.

Other uses of CCW exist in various domains but are less common and context-specific. The two meanings above cover the most frequent references in technical and legal discussions.
