Year, month and day

type Year = Integer Source #

Year of Common Era.

type MonthOfYear = Int Source #

Month of year, in range 1 (January) to 12 (December).

type DayOfMonth = Int Source #

Day of month, in range 1 to 31.

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.

pattern YearMonthDay :: Year -> MonthOfYear -> DayOfMonth -> Day Source #

Bidirectional abstract constructor for the 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?

Week

data DayOfWeek Source #

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.
