Writing a condition logics in kotlin in a better way in kotlin - algorithm

Question

I have a following condition logic and want to make it simple, is there a way to make it better without too much || && ? Some sample or example will be lovely! I would love to hear from you!
Logic that I want to achieve
From 0:00 on and 3 days before the birth month,
condition is the birth month is once or January 31st and
the present is run every December 29-31
val birthYear = child.birthYear!!.toInt()
val birthMonth = child.birthMonth!!.toInt()
val date = DateTime()
val year = date.year
val month = date.month
val day = date.day
val maxDayOfMonth = date.maxDayOfMonth
class DateTime {
private var mCalendar: Calendar = Calendar.getInstance().also { it.clear() }
val year: Int
get() = mCalendar.get(Calendar.YEAR)。。。。。
The following is the logic that I want to make it simpler
return date.year > child.birthYear!!.toInt() &&
((birthMonth == 1 && month == 12 || birthMonth - 1 == month)
&& day >= maxDayOfMonth - 2 || birthMonth == month)
