This date won’t generate any error for there are no 30 days in Feb but it’ll show this date as 1st MARCH 2020.
Similarly the following translations are there
=DATE(2020,13,01)

1st JAN 2021 as there are no 13 months in an year but it’ll create one year of the twelve months and start the next month and year.
