How to get date 7 days ago to today in Kotlin?

I want to get date from 7 days ago to today in Kotlin. Any suggestions? This is what I have so far

val date = Calendar.getInstance()

val yesterday = Calendar.getInstance()

yesterday.add(Calendar.DATE,-1)

var todayOrYesterday:String?

var todayDate = date.time

while (todayDate > yesterday.time){

val formatter = SimpleDateFormat("EEEE, d MMMM yyyy")

val format = formatter.format(todayDate)

println(format)

todayOrYesterday = if (DateUtils.isToday(date.timeInMillis)) {
"Today"
}else "Yesterday"

date.add(Calendar.DATE,-7)
}

Simply use,

val date = Calendar.getInstance() // 19-01-2018
date.add(Calendar.DATE, -7) // 12-01-2018

Use this function, pass the days ago you want:

fun getDaysAgo(daysAgo: Int): Date {
val calendar = Calendar.getInstance()
calendar.add(Calendar.DAY_OF_YEAR, -daysAgo)

return calendar.time
}

An alternative is to use [Joda Time][1] ([Joda Time for Android][2]). This library has a really nice API.

DateTime.now().minusDays(7)

And you can call `.toDate()` if you need a Java-Date object.
