"Light of day" is a common idiomatic expression that refers to the natural illumination provided by the sun during daylight hours. It symbolizes the visibility and clarity brought about by sunlight, contrasting with darkness. The phrase can be used literally, describing the presence of sunlight that illuminates the surroundings and allows for clear vision. It highlights the notion that during the daytime, objects, landscapes, and people are easily perceptible, making it easier to navigate and go about daily activities.
Metaphorically, the expression "light of day" is often used to depict the exposure or revelation of hidden or concealed truths or information, evoking a sense of bringing something into public view or acknowledging its existence. It suggests the notion of unveiling or scrutinizing something that was previously unknown, obscured, or covered up. When a subject or situation is brought into the light of day, it is made visible, transparent, and accessible to scrutiny, and hence, it is no longer concealed or hidden.
The phrase can also be employed in a figurative sense to emphasize the passage of time or the surpassing of obstacles or challenges. It signifies the triumph of overcoming difficulties, setbacks, or secrets, with the notion that these obstacles are overcome and resolved as they are brought to light. In this context, "light of day" implies progress, resolution, or achievement resulting from facing and resolving previously obscured or unresolved matters.
