Can type more than 4 digits into the year field.

Typing, for example, 04/14/20123 looks like it is accepted. However, by inspecting the hidden , I can see that the real date value stored is 04/14/0123.

@ivanjonas Perfect, thank you! I see now that the year 100,000 is perfectly acceptable as a year, although undesirable in our particular case. This solves the problem so thanks for coming back to me, I appreciate your time.

Turns out it was pretty simple and straightforward.

const MAX_DATE = new Date('9999-12-31T23:59:59.999');

<DateTimePicker
  value={isValidDate ? value : new Date()}
  minDate={minValue}
  maxDate={MAX_DATE}
  ...
