每天修改脚本

Question

我需要将此脚本从“天”（周一至周日）脚本更改为日期（例如，2018年6月1日至6月7日）脚本。我该如何修改此脚本？为此需要您的帮助。

我有这样的Google Adwords脚本

// script to change budget by day of week
// Jon Gritton 2016
// user vars
var BUDG_NAME = "Shared budget S104 (CX - High)";
var B_MON = 
500000
;
var B_TUE = 
500000
;
var B_WED = 
500000
;
var B_THU = 
500000
;
var B_FRI = 
500000
;
var B_SAT = 
500000
;
var B_SUN = 
500000
;

function main() {
 setBudget(getBudgetToday());
}

function getBudgetToday() {
 var budgArray = [B_SUN,B_MON,B_TUE,B_WED,B_THU,B_FRI,B_SAT];
 var d = new Date(Utilities.formatDate(new Date(), AdWordsApp.currentAccount().getTimeZone(), "MMM dd,yyyy HH:mm:ss"));
 var today = d.getDay();
 return budgArray[today];
}

function setBudget(budgetToday) {
 Logger.log("Budget for today is: " + budgetToday);
 var budgetIter = AdWordsApp.budgets()
 .withCondition("BudgetName = '" + BUDG_NAME + "'")
 .get()
 while (budgetIter.hasNext()) {
 var thisBudget = budgetIter.next();
 thisBudget.setAmount(budgetToday);
 }
}
