class ViewHolder (

    fun bind(date: Date){
        val currentDateTime = LocalDateTime.now()
        val format = SimpleDateFormat("M/d", Locale.US)
        val cal = Calendar.getInstance(Locale.US)

        val currentDate = Calendar.getInstance(Locale.US)

        val currentMonth = currentDate[Calendar.MONTH]


        binding.textDate.text = currentDateTime.toString()
