What does this do?

The extension in date to return a calendar object looks quite complicated.

var Date.calendar: Calendar
    get() = Calendar.getInstance().apply { time = this@calendar }
    set(value) {
        time = value.timeInMillis
    }

Isn't that the equivalent of this?

val Date.calendar: Calendar
    get() = Calendar.getInstance().apply { timeInMillis = this@calendar.time }

Nope it wouldn't be -- your proposed change is a val instead of var, therefore it doesn't have a setter and would not be able to be reassigned (aka, setting a new Calendar on the Date)
