addDays :: Integer -> Day -> Day Source
diffDays :: Day -> Day -> Integer Source
toGregorian :: Day -> (Integer, Int, Int) Source
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 Source
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 Source
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 Source
Show in ISO 8601 format (yyyy-mm-dd)
gregorianMonthLength :: Integer -> Int -> Int Source
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 Source
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 Source
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 Source
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 Source
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.
isLeapYear :: Integer -> Bool Source
Is this year a leap year according to the proleptic Gregorian calendar?
