scaleCalendarDiffDays :: Integer -> CalendarDiffDays -> CalendarDiffDays #

Scale by a factor. Note that scaleCalendarDiffDays (-1) will not perfectly invert a duration, due to variable month lengths.

Gregorian calendar

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

Convert to proleptic Gregorian calendar. First element of result is year, second month number (1-12), third day (1-31).

fromGregorian :: Integer -> Int -> Int -> Day #

Convert from proleptic Gregorian calendar. First argument is year, second month number (1-12), third day (1-31). Invalid values will be clipped to the correct range, month first, then day.

fromGregorianValid :: Integer -> Int -> Int -> Maybe Day #

Convert from proleptic Gregorian calendar. First argument is year, second month number (1-12), third day (1-31). Invalid values will return Nothing

showGregorian :: Day -> String #

Show in ISO 8601 format (yyyy-mm-dd)

gregorianMonthLength :: Integer -> Int -> Int #

The number of days in a given month according to the proleptic Gregorian calendar. First argument is year, second is month.

addGregorianMonthsClip :: Integer -> Day -> Day #

Add months, with days past the last day of the month clipped to the last day. For instance, 2005-01-30 + 1 month = 2005-02-28.

addGregorianMonthsRollOver :: Integer -> Day -> Day #

Add months, with days past the last day of the month rolling over to the next month. For instance, 2005-01-30 + 1 month = 2005-03-02.

addGregorianYearsClip :: Integer -> Day -> Day #

Add years, matching month and day, with Feb 29th clipped to Feb 28th if necessary. For instance, 2004-02-29 + 2 years = 2006-02-28.

addGregorianYearsRollOver :: Integer -> Day -> Day #

Add years, matching month and day, with Feb 29th rolled over to Mar 1st if necessary. For instance, 2004-02-29 + 2 years = 2006-03-01.

addGregorianDurationClip :: CalendarDiffDays -> Day -> Day #

Add months (clipped to last day), then add days

addGregorianDurationRollOver :: CalendarDiffDays -> Day -> Day #

Add months (rolling over to next month), then add days

diffGregorianDurationClip :: Day -> Day -> CalendarDiffDays #

Calendrical difference, with as many whole months as possible

diffGregorianDurationRollOver :: Day -> Day -> CalendarDiffDays #

Calendrical difference, with as many whole months as possible. Same as diffGregorianDurationClip for positive durations.

isLeapYear :: Integer -> Bool #

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

Week

data DayOfWeek #

Instances

Enum DayOfWeek

"Circular", so for example [Tuesday ..] gives an endless sequence. Also: fromEnum gives [1 .. 7] for [Monday .. Sunday], and toEnum performs mod 7 to give a cycle of days.
