How to set the interval of sending messages from the bot?

const ONE_MIN = 60 * 1000;
const ONE_HOURS = 60 * 60 * 1000;

let isSentFridayMessage = false;
let startEvery22HoursTimer = new Date();

setInterval(() => {
 // Every Friday at 18 o'clock
 let currentDate = new Date();
 if (currentDate.getDay() == 5 && currentDate.getHours == 18 && !isSentFridayMessage) {
 // do something 
 isSentFridayMessage = true;
 } else {
 isSentFridayMessage = false
}

 // Every 22 hours
 if (startEvery22HoursTimer < new Date(Date.now() - 22 * ONE_HOURS)) {
 startEvery22HoursTimer = new Date();
 // do something
}

}, ONE_MIN)
