next :: (Eq a, Bounded a, Enum a) => a -> a Source #

Permite iterar sobre datos enumerables de forma circular. Una vez se llega al último elemento, el siguiente será el primero.

>>> next October
November
>>> next December
January

Permite la generacion de una lista infinita:

>>> take 11 $ iterate next Saturday
[Saturday,Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday,Sunday,Monday,Tuesday]

getMonth :: Day -> Month Source #

Indica el mes al que pertenece un día.

>>> getMonth $ fromGregorian 2019 1 14
