You can look for a particular date by modifying vaccinationDate value at line 42 to DD-MM-YYYY format. By default, it checks for the next day availabilities.

const transporter = nodemailer.createTransport({
  service: "gmail",
  auth: {
    user: process.env.GMAIL_EMAIL,
    pass: process.env.GMAIL_PASS,
  },
});

const sendEmail = (text, send_to) => {
  transporter.sendMail(
    {
      from: process.env.GMAIL_EMAIL,
      to: send_to,
      subject: "Cowin available",
      text,
    },
    (err, info) => {
      if (err) {
        console.log(err);
      } else {
        console.log(info);
      }
    }
  );
};
