DateTools is a date manipulation library for iOS applications that provides utilities for date arithmetic, range management, and relative time formatting. It functions as a set of tools to shift dates by specific units, calculate durations between timestamps, and convert dates into localized, human-readable strings.
The library specializes in the analysis of time spans, offering systems to define, compare, and organize overlapping or sequential time periods. It includes logic to determine chronological relationships, such as whether dates fall within specific windows or how different time periods intersect.
Additional capabilities include the extraction of specific calendar components, such as hours or days, and the conversion of timestamps into relative time descriptions based on the current moment.
