Pattern to match date in YYYY-MM-DD format on Linux machine

Hi Expert,

Request your help.
For date validation in csv file, i have written below code for linux machine
I want the date to be in format 2017-05-11(YYYY-MM-DD), if not present in this format the error should be printed.
Could you please help in finding the right pattern to match above date format

Code:
if ($14 !~ /^[0-9]{4}-(0[1-9]|1[0-2])-(0[1-9]|[1-2][0-9]|3[0-1])$/) {print "Error 131: Incorrect DocumentDate pattern", "Field position 14, Linenumber:"NR,$0}

but it is not working and if date is present in correct format then also i am getting the error as below
Code:
Error 131: Incorrect DocumentDate pattern Field position 14, Linenumber:2
