How to create an array of days starting with today and going back the last 30 days in Kotlin

Answer 1

import java.time.LocalDate

fun getLast30Days(): Array<Int> {
    // Get today's date
    val today = LocalDate.now()

    // Create an array to store the last 30 days (day of the month only)
    val days = Array(30) { i ->
        today.minusDays(i.toLong()).dayOfMonth // Extract and store only the day of the month
    }

    return days
}

fun main() {
    // Get the last 30 days by calling the function
    val days = getLast30Days()

    println("Days:")
    for (day in days) {
        println(day)
    }
}
