moment.js 时间差

npm install moment

const moment = require('moment');

// 创建两个日期对象
const start = moment('2023-01-01');
const end = moment('2023-01-10');

// 计算时间差
const duration = moment.duration(end.diff(start));

// 输出时间差
console.log(duration.days()); // 输出: 9
console.log(duration.hours()); // 输出: 216
console.log(duration.minutes()); // 输出: 12960
console.log(duration.seconds()); // 输出: 777600

const formattedDuration = duration.humanize();
console.log(formattedDuration); // 输出: "9 days"

const start = moment.utc('2023-01-01');
const end = moment.utc('2023-01-10');
const duration = moment.duration(end.diff(start));
console.log(duration.days()); // 输出: 9

const { differenceInDays } = require('date-fns');
const start = new Date('2023-01-01');
const end = new Date('2023-01-10');
console.log(differenceInDays(end, start)); // 输出: 9
