DateComponents are specified in terms of units (e.g. year, month, day, hour, and minute), and are evaluated using a calendar and time zone.

Foundation's Calendar wraps absolute points in time in systems which provide features for calculation and comparison of dates.
Locale

Locales provide information about linguistic, cultural, and technological conventions for use in formatting data for presentation.
Calendar Components and Symbols

Calendars employ an enumeration for the various components of their dates, and lists of localized symbol Strings.

Foundation's Date Formatters convert between dates and their textual representations. They provide the human-readable Strings that your users will see.
ISO 8601

ISO 8601 is a widely-used standard for date representation. It's a human-readable string, but as accurate as a TimeInterval instance.
