scaleCalendarDiffDays :: Integer -> CalendarDiffDays -> CalendarDiffDays Source #

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

# Gregorian calendar

toGregorian :: Day -> (Year, MonthOfYear, DayOfMonth) Source #

Convert to proleptic Gregorian calendar.

fromGregorian :: Year -> MonthOfYear -> DayOfMonth -> Day Source #

Convert from proleptic Gregorian calendar. Invalid values will be clipped to the correct range, month first, then day.

fromGregorianValid :: Year -> MonthOfYear -> DayOfMonth -> Maybe Day Source #

Convert from proleptic Gregorian calendar. Invalid values will return Nothing

showGregorian :: Day -> String Source #

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

gregorianMonthLength :: Year -> MonthOfYear -> DayOfMonth Source #

The number of days in a given month according to the proleptic Gregorian calendar.

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.

addGregorianDurationClip :: CalendarDiffDays -> Day -> Day Source #

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

addGregorianDurationRollOver :: CalendarDiffDays -> Day -> Day Source #

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

diffGregorianDurationClip :: Day -> Day -> CalendarDiffDays Source #

Calendrical difference, with as many whole months as possible

diffGregorianDurationRollOver :: Day -> Day -> CalendarDiffDays Source #

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

isLeapYear :: Year -> Bool Source #

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

gmapMo :: MonadPlus m => (forall d. Data d => d -> m d) -> DayOfWeek -> m DayOfWeek Source #

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.
