var (
	ErrNotSunday         = errors.New("date must be a Sunday")
	ErrFromAfterTo       = errors.New("'from' must be before 'to'")
	ErrDateRangeExceeded = errors.New("date range exceeded")
)

Functions ¶

func ParseSundayDate ¶ added in v1.3.15

func ParseSundayDate(value string) (time.Time, error)

ParseSundayDate parses value in "2006-01-02" format and verifies it falls on a Sunday, returning ErrNotSunday otherwise.

func ValidateDateRange ¶ added in v1.3.19

func ValidateDateRange(from, to time.Time, maxDays int) error

ValidateDateRange checks that from precedes to and the span does not exceed maxDays.

func ValidateSunday ¶

func ValidateSunday(value string) error

ValidateSunday reports whether value is a valid "2006-01-02" date falling on a Sunday.

Types ¶

type DateRange ¶ added in v1.3.19

type DateRange struct {
	From    time.Time
	To      time.Time
	MaxDays int
}

DateRange is an inclusive [From, To] interval. MaxDays bounds the span; zero means MaxDateRangeDays.

func (DateRange) Validate ¶ added in v1.3.19

func (dr DateRange) Validate() error

Validate checks that From precedes To and the span does not exceed MaxDays.
