// Package date provides functionality for working with dates.
// It implements a light-weight Date type that is storage-efficient
// and convenient for calendrical calculations and date parsing and formatting
// (including years outside the [0,9999] interval).
//
// Subpackages provide:
//
// * `clock.Clock` which expresses a wall-clock style hours-minutes-seconds with millisecond precision.
//
// * `period.Period` which expresses a period corresponding to the ISO-8601 form (e.g. "PT30S").
//
// * `timespan.DateRange` which expresses a period between two dates.
//
// * `timespan.TimeSpan` which expresses a duration of time between two instants.
//
// * `view.VDate` which wraps `Date` for use in templates etc.
//
// Credits
//
// This package follows very closely the design of package time
// (http://golang.org/pkg/time/) in the standard library, many of the Date
// methods are implemented using the corresponding methods of the time.Time
// type, and much of the documentation is copied directly from that package.
