Calculating previous months from Date() duplicates a month

I am trying to 12 previous months from today, but it displays

Date to start with - Mon May 30 22:57:30 GMT+01:00 2022

Months displayed are - these are the values in the monthsArray, Month March 2022 is displayed twice

April 2022
March 2022 (DISPLAYED TWICE)
March 2022 (DISPLAYED TWICE)
February 2022
January 2022
December 2021
November 2021
October 2021
September 2021
August 2021
July 2021
June 2021

This is the logic to display months

    val monthsArray: ArrayList<String> = ArrayList()
    val date = Date()
    var i = 1
    while (i <= 12) {
        date.month = date.month - 1
        monthsArray.add(readableSpinnerItemDate(date.time))
        i++
    }

Could you please suggest what might be wrong here please

I think this should do what you are looking for.

val monthsArray = (0..11).map { LocalDateTime.now().minusMonths(it.toLong()).format(DateTimeFormatter.ofPattern("MMMM yyyy")) }
