获取季度的开始/结束日期

Question

我如何计算某个日期的季度开始/结束日期？如果我给出了"2012-10-11"我想要的方法示例:{ :begin_date => '2012-10-01', :end_date => '2012-12-31' }

def quarter_dates(date = Date.today)
  # TODO...
  return {
    :begin_date => begin_date,
    :end_date => end_date
  }
end

Answer 1

的ActiveSupport提供beginning_of_quarter和end_of_quarter只是这样的:

require 'active_support/core_ext/date/calculations'

def quarter_dates(date = Date.today)
  {
    begin_date: date.beginning_of_quarter,
    end_date: date.end_of_quarter
  }
end
