如何使用moment js查找一个季度内的剩余天数

// 引入 moment.js
const moment = require('moment');

// 获取当前日期
const now = moment();

// 获取当前季度的最后一天
let endOfQuarter;
switch (now.month()) {
  case 0: case 1: case 2:
    endOfQuarter = moment([now.year(), 2, 31]); // Q1
    break;
  case 3: case 4: case 5:
    endOfQuarter = moment([now.year(), 5, 31]); // Q2
    break;
  case 6: case 7: case 8:
    endOfQuarter = moment([now.year(), 8, 30]); // Q3
    break;
  case 9: case 10: case 11:
    endOfQuarter = moment([now.year() + 1, 0, 1]).subtract(1, 'days'); // Q4
    break;
}

// 计算剩余天数
const remainingDays = endOfQuarter.diff(now, 'days');

console.log(`当前季度剩余天数：${remainingDays}`);
