#

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

valueaddGregorianDurationRollOver :: CalendarDiffDays -> Day -> Day

#

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

valueaddGregorianMonthsClip :: 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.

valueaddGregorianMonthsRollOver :: 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.

valueaddGregorianYearsClip :: 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.

valueaddGregorianYearsRollOver :: 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.

valuediffGregorianDurationClip :: Day -> Day -> CalendarDiffDays

#

Calendrical difference, with as many whole months as possible

valuediffGregorianDurationRollOver :: Day -> Day -> CalendarDiffDays

#

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