PeriodicalDates.jl

This packages makes it easier to work with monthly, quarterly, or yearly dates. It defines three types:

• A MonthlyDate <: TimeType type

  ulia> using Dates, PeriodicalDates
  ulia> dt = MonthlyDate(1990, 1)
   Alternatively, construct from a date
  ulia> dtm = MonthlyDate(Date(1990, 1))
   Alternatively, contruct from a string with default dateformat"yyyy-mm"
  ulia> dtm = MonthlyDate("1990-01")
   or any other DateFormat
  ulia> dtm = MonthlyDate("1990/01", "yyyy/mm")
   Arithmetic works as expected
  ulia> dtm + Month(1)
  ulia> Date(dtm)
   1990-01-01
  
  

• A QuarterlyDate <: TimeType type

  ulia> using Dates, PeriodicalDates
  ulia> dtq = QuarterlyDate(1990, 1)
   Alternatively, construct from a date
  ulia> dtq = QuarterlyDate(Date(1990, 1))
   Alternatively, contruct from a string with default dateformat"yyyy-Qq"
  ulia> dtq = QuarterlyDate("1990-Q1") 
   or any other DateFormat
  ulia> dtq = QuarterlyDate("1990/04", "yyyy/mm")
   Arithmetic works as expected
  ulia> dtq + Quarter(3)
  ulia> Date(dtq)
   1990-04-01
  

• A YearlyDate <: TimeType type (for the sake of consistency)

  ulia> using Dates, PeriodicalDates
  ulia> dty = YearlyDate(1990)
   Arithmetic works as expected
  ulia> dty + Year(1)
  ulia> Date(dty)
   1990-01-01
