type Year = Integer #

Year of Common Era (when positive).

pattern CommonEra :: Integer -> Year #

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

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.
