[Easy way with Python Solved 🥱🥱]
import re
from datetime import datetime
da = input()
de = input()
a = datetime.strptime(da, '%B %d, %Y').strftime('%d/%m/%Y')
b = datetime.strptime(de, '%B %d, %Y').strftime('%d/%m/%Y')
aa = datetime.strptime(a,'%d/%m/%Y')
bb = datetime.strptime(b,'%d/%m/%Y')
diff = bb -aa
print(diff.days)
