period_boundaries {busdater}R Documentation

Get date's business period boundary (deprecated).


The period_boundaries is a deprecated function. It will shift the input date vector by a number of months and years i.e. date + offset_period * offset_type. It will handle the typical business date arithmetic.


period_boundaries(date = Sys.Date(), offset_period = 0,
  offset_type = "year", bus_period = "FY", boundary = "1st day",
  optFYstart = getOption("busdaterFYstart", default = "07-01"))



A date vector for which financial year is required. Date must be POSIXct or POSIXlt or Date objects.


A positive or negative number coercible to integer to shift the year by, e.g. in the case of FY, -1 for previous year, 1 for next year. More generally in page_boundaries function it is a number of periods of a specified period type


It is either "month" or "year"


It is either "FY" for financial year, "CE" for calendar year or "M" for month


Either "1st day" for the first day of the period or "last day" for the end of the period.


A string in the format of "MM-DD" representing the start of financial year, e.g. "01-01" for 1st of January or "07-01" for 1st of July. This package caters for financial years that have a fixed start date. It does not cater for moving dates e.g. last Friday of September.
