Instance details

Defined in Data.Time.Format.ISO8601

type Year = Integer Source #

Year of Common Era.

type DayOfYear = Int Source #

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 Source #

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

toOrdinalDate :: Day -> (Integer, Int) #

Convert to ISO 8601 Ordinal Date format. First element of result is year (proleptic Gregoran calendar), second is the day of the year, with 1 for Jan 1, and 365 (or 366 in leap years) for Dec 31.

fromOrdinalDate :: Integer -> Int -> 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 Source #

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 :: Integer -> Int -> 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 :: Integer -> Bool #

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

mondayStartWeek :: Day -> (Int, 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 -> (Int, 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

:: Integer

Year.

-> Int

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

:: Integer

Year.

-> Int

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

:: Integer

Year.

-> Int

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

:: Integer

Year.

-> Int

Sunday-starting week number (as %U in formatTime).

-> Int

Day of week. Sunday is 0, Saturday is 6 (as %w in formatTime).

-> Maybe Day
