PeriodicalDates.jl

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

• A MonthlyDate <: TimeType type

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

• A QuarterlyDate <: TimeType type

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

• A YearlyDate <: TimeType type, mainly for consistency

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