[Python] CS50P PSET 3 "Outdated": I am failing one testcase

I'm attempting this problem: https://cs50.harvard.edu/python/2022/psets/3/outdated/ which is basically a program that takes input in "month/day/year" format or "month day, year" format and outputs in YYYY-MM-DD format. After running my code through check50 (a program that tests your code), I passed all the conditions except 1: "input of September 8 1636 results in reprompt" Do I make the program require the "," be in the date?

months = [
"January",
"February",
"March",
"April",
"May",
"June",
"July",
"August",
"September",
"October",
"November",
"December"
]

while True:
try:
date = input("Date: ")
month, day, year = date.split("/")
if (int(month)>=1 and int(month)<=12) and ( 1 <= int(day) <= 31):
day = int(day)
if day < 10:
day = f"{int(day):02}"
if int(month) <10:
month = f"{int(month):02}"
break
except(ValueError):
try:
month, day, year = date.split(" ")
day = day.strip(",")
if month in months and ( 1 <= int(day) <= 31):
for m in months:
if m == month:
month = months.index(m) + 1
month = f"{int(month):02}"
day = f"{int(day):02}"
break
except:
pass
print(f"{year}-{month}-{day}")
