How to operate on days in Kotlin?

Question

I can get the current time like System.currentTimeInMillis(). But I really don't need this granularity in the millisecond range. A type which gets me a rough day date like 22.11.2021 is enough for my purposes.

I also would appreciate operations like incrementing the next 14 days etc.

You can use LocalDate as follows:

fun main() {
    val currentDate = LocalDate.now()
    println(currentDate)
    val futureDate = currentDate.plusDays(14)
    println(futureDate)
}
