    fun test1(){

        val d1: LocalDateTime = LocalDateTime.parse("2023-05-06 00:00:00", DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))
        val d2: LocalDateTime = LocalDateTime.parse("2023-05-07 15:12:00", DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))

        val d3: LocalDate = LocalDate.parse("2023-05-06 00:00:00", DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))
        val d4: LocalDate = LocalDate.parse("2023-05-07 15:12:00", DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))

        val diff: Duration = Duration.between(d1, d2)
        val period: Period = Period.between(d3, d4)

        val diffDays: Long = diff.toDays()
        val years: Int = Math.abs(period.getYears())
        val months: Int = Math.abs(period.getMonths())
        val days: Int = Math.abs(period.getDays())
        println("Diffrence between dates is : " + diffDays + "days")
        println("Diffrence is : $years year, $months months, $days days")
        println(d1.month.value)
    }

结果

Diffrence between dates is : 1days
Diffrence is : 0 year, 0 months, 1 days
