interval(
  date_from :: Date.t(),
  date_to_or_count :: Date.t() | non_neg_integer(),
  precision()
) :: [Date.t()]

Returns an Enumerable list of dates of a given precision of either :years, :quarters, :months, :weeks or :days

Arguments

• date_from is a any Date.t that is the start of the sequence

• date_to_or_count is upper bound of the sequence as a Date.t or the number of dates in the sequence to be generated

• precision is one of :years, :quarters, :months, :weeks or :days

The sequence is generated starting with date_from until the next date in the sequence would be after date_to.

Notes

The sequence can be in ascending or descending date order based upon whether date_from is greater than date_to.

Returns

• A list of dates

Examples

iex> d = ~D[2019-01-31]
~D[2019-01-31]
iex> d2 = ~D[2019-05-31]
~D[2019-05-31]
iex> Cldr.Calendar.interval d, 3, :months
[~D[2019-01-31], ~D[2019-02-28], ~D[2019-03-31]]
iex> Cldr.Calendar.interval d, d2, :months
[~D[2019-01-31], ~D[2019-02-28], ~D[2019-03-31],
 ~D[2019-04-30], ~D[2019-05-31]]
