18581924

18581924 is most commonly used in biographical writing as shorthand for a person's lifespan, indicating that the individual was born in 1858 and died in 1924. In this context the years are typically presented with an en dash as 1858–1924 and placed after the person's name (for example, Jane Doe (1858–1924)).

When the exact birth or death dates are uncertain, other notations may appear, such as ca. 1858–1924 (circa), b. 1858, or d. 1924. The flourished period for a person or family may be written as fl. 1900s to indicate the time during which they were active.

Beyond individuals, 1858–1924 can designate a time span for events or publications, though in practice the form is most common in biographical references. The convention is part of standard date notation used by libraries, archives, and encyclopedia projects to provide compact, comparable metadata.

Historical context is implied by the range; the years align with late 19th century developments and the early 20th century, including industrialization, modern science, and the aftermath of World War I. The notation itself does not convey any facts about a person or event beyond birth and death years unless supplemented by additional information.
