How to know what today is, in discord.js

I want to make bot that know what day is today, i have example code below but i dont know how to fix this.

  client.on("message", msg =>{
  if (msg.content === "!today"){
    If (Today is Sunday){
        msg.reply("Time to Holiday")
      }
    else if(Today is monday){
        msg.reply("Time to work")
      }
  }
 });

>Solution :

new Date() gives you the current date and time. It has a method .getDay() which gives you the day of the week as a number. Sunday is 0; Monday is 1. So:

const dayOfWeek = new Date().getDay();

if (dayOfWeek === 0) { // is it Sunday?

Note that this is the bot server date and time. Different users might be on different days, due to time zones.
