If cron-like functionality from within Node is what you want, you can try node-cron

const cron = require("node-cron");
const express = require("express");
const fs = require("fs");

app = express();

frequency="Yearly"
pattern=""

switch(frequency) {
  case "Daily":
    pattern = "0 0 * * *"
    break;
  case "Monthly":
    pattern = "0 0 1 * *"
    break;
  default:
    pattern = "* * * * *"
    frequency = "every minute"
}

// schedule tasks to be run on the server
cron.schedule(pattern, function () {
  console.log("running a task " + frequency);
});

app.listen(3128);

Example borrowed from here Node.js Cron Jobs By Examples

Added some extra switch case logic to demonstrate a possible workflow for your task at hand.
