function dateTime(startDate,dayTime){ //起始日期, 天数

   var date = new Date(startDate);
   var newDate = new Date(date.getFullYear(),date.getMonth(),date.getDate()+dayTime);


   var year1 = date.getFullYear();
   var month1 = date.getMonth()+1;
   var day1 = date.getDate();


   var year2 = newDate.getFullYear();
   var month2 = newDate.getMonth()+1;
   var day2 = newDate.getDate();
   return `起始日期: ${year1}-${month1}-${day1} ~ 有效期: ${year2}-${month2}-${day2}`;
}
dateTime('2023-04-06',720)  //'2023-4-6 ~ 2025-3-26'
