// 判断是否为工作日
function isWorkingDay(date) {
  // 获取星期几（0表示星期日，1表示星期一，以此类推）
  const dayOfWeek = date.getDay();
console.log(dayOfWeek,9)
  // 判断是否为周末（星期六或星期日）
  if (dayOfWeek === 0 || dayOfWeek === 6) {

// 获取延后几天后的日期
function getDelayedDate(date, days) {
  const delayedDate = new Date(date.getTime());
  console.log(date,delayedDate)
  delayedDate.setDate(date.getDate() + days);

// 示例用法
const currentDate = new Date(); // 当前日期
const delayedDate = getDelayedDate(currentDate, 5); // 延后3天后的日期

console.log("当前日期:", currentDate.toLocaleDateString());
console.log("延后3天后的日期:", delayedDate.toLocaleDateString());
console.log("延后3天后是否为工作日:", isWorkingDay(delayedDate));
