Instance details Defined in Data.Time.Format.ISO8601 Methods iso8601Format :: Format Day #

type Year = Integer #

Year of Common Era (when positive).

type DayOfYear = Int #

Day of year, in range 1 (January 1st) to 366. December 31st is 365 in a common year, 366 in a leap year.

type WeekOfYear = Int #

Week of year, by various reckonings, generally in range 0-53 depending on reckoning.

toOrdinalDate :: Day -> (Year, DayOfYear) #

Convert to ISO 8601 Ordinal Date format.

fromOrdinalDate :: Year -> DayOfYear -> Day #

Convert from ISO 8601 Ordinal Date format. Invalid day numbers will be clipped to the correct range (1 to 365 or 366).

pattern YearDay :: Year -> DayOfYear -> Day #

Bidirectional abstract constructor for ISO 8601 Ordinal Date format. Invalid day numbers will be clipped to the correct range (1 to 365 or 366).

fromOrdinalDateValid :: Year -> DayOfYear -> Maybe Day #

Convert from ISO 8601 Ordinal Date format. Invalid day numbers return `Nothing`

showOrdinalDate :: Day -> String #

Show in ISO 8601 Ordinal Date format (yyyy-ddd)

isLeapYear :: Year -> Bool #

Is this year a leap year according to the proleptic Gregorian calendar?

mondayStartWeek :: Day -> (WeekOfYear, Int) #

Get the number of the Monday-starting week in the year and the day of the week. The first Monday is the first day of week 1, any earlier days in the year are week 0 (as `%W` in `formatTime`). Monday is 1, Sunday is 7 (as `%u` in `formatTime`).

sundayStartWeek :: Day -> (WeekOfYear, Int) #

Get the number of the Sunday-starting week in the year and the day of the week. The first Sunday is the first day of week 1, any earlier days in the year are week 0 (as `%U` in `formatTime`). Sunday is 0, Saturday is 6 (as `%w` in `formatTime`).

fromMondayStartWeek #

Arguments

:: Year | Year.
-> WeekOfYear | Monday-starting week number (as `%W` in `formatTime`).
-> Int | Day of week. Monday is 1, Sunday is 7 (as `%u` in `formatTime`).
-> Day |

The inverse of `mondayStartWeek`. Get a `Day` given the year, the number of the Monday-starting week, and the day of the week. The first Monday is the first day of week 1, any earlier days in the year are week 0 (as `%W` in `formatTime`).

fromMondayStartWeekValid #

Arguments

:: Year | Year.
-> WeekOfYear | Monday-starting week number (as `%W` in `formatTime`).
-> Int | Day of week. Monday is 1, Sunday is 7 (as `%u` in `formatTime`).
-> Maybe Day |

fromSundayStartWeek #

Arguments

:: Year | Year.
-> WeekOfYear | Sunday-starting week number (as `%U` in `formatTime`).
-> Int | Day of week Sunday is 0, Saturday is 6 (as `%w` in `formatTime`).
-> Day |

The inverse of `sundayStartWeek`. Get a `Day` given the year and the number of the day of a Sunday-starting week. The first Sunday is the first day of week 1, any earlier days in the year are week 0 (as `%U` in `formatTime`).

fromSundayStartWeekValid #

Arguments

:: Year | Year.
-> WeekOfYear | Sunday-starting week number (as `%U` in `formatTime`).
-> Int | Day of week. Sunday is 0, Saturday is 6 (as `%w` in `formatTime`).
-> Maybe Day |
