weekly joins JS

I'm using ENMAP btw for the weekly joins
  {
      CronJob
  } = require('cron'),
  Enmap = require('enmap')

client.join = new Enmap({name: "joins", autoFetch: true, fetchAll: true})
const job = new CronJob('0 12 * * Sun', () => {
  client.joins.clear()
}, null, true, 'America/Los_Angeles')

Index.js file ^^

guildMemberAdd event

client.joins.ensure(member.guild.id, {
    "monday": 0,
    "tuesday": 0,
    "wednesday": 0,
    "thursday": 0,
    "friday": 0,
    "saturday": 0,
    "sunday": 0,
  })

  let days = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];
  let dayName = days[new Date().getDay()].toLowerCase()

  client.joins.inc(member.guild.id, dayName)


Command file.js
        const guildJoins = client.joins.ensure(message.guild.id, {
            "monday": 0,
            "tuesday": 0,
            "wednesday": 0,
            "thursday": 0,
            "friday": 0,
            "saturday": 0,
            "sunday": 0,
        })

        const chart = {
            type: 'line',
            data: {
                labels: ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday'],
                datasets: [{
                    label: 'Joins',
                    data: Object.values(guildJoins)
                }]
            }
        }

        let enChart = encodeURIComponent(JSON.stringify(chart))
        const chartUrl = `https://quickchart.io/chart?c=${enChart}&backgroundColor=(rgb(47,%2049,%2054))`;
        message.channel.send(new Discord.MessageAttachment(chartUrl, "chart.png"))
