Methods
periodFirstDay :: p -> Day Source #
Returns the first Day in a period of days.
periodLastDay :: p -> Day Source #
Returns the last Day in a period of days.
dayPeriod :: Day -> p Source #
Get the period this day is in.
scaleCalendarDiffDays :: Integer -> CalendarDiffDays -> CalendarDiffDays Source #
Scale by a factor. Note that scaleCalendarDiffDays (-1) will not perfectly invert a duration, due to variable month lengths.
data CalendarDiffDays Source #
Constructors

Instances
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.
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
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.
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.
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
gregorianMonthLength :: Year -> MonthOfYear -> DayOfMonth Source #
The number of days in a given month according to the proleptic Gregorian calendar.

Is this year a leap year according to the proleptic Gregorian calendar?
pattern April :: MonthOfYear Source #

dayOfWeekDiff a b = a - b in range 0 to 6.
The number of days from b to the next a.
weekAllDays :: DayOfWeek -> Day -> [Day] Source #
Returns a week containing the given Day where the first day is the
DayOfWeek specified.
Examples:
>>>weekAllDays Sunday (YearMonthDay 2022 02 21)[YearMonthDay 2022 2 20 .. YearMonthDay 2022 2 26]

Since: time-1.12.2
weekFirstDay :: DayOfWeek -> Day -> Day Source #
Returns the first day of a week containing the given Day.
Examples:
>>>weekFirstDay Sunday (YearMonthDay 2022 02 21)YearMonthDay 2022 2 20
>>>weekFirstDay Monday (YearMonthDay 2022 02 21)YearMonthDay 2022 2 21
