根据月份数生成对应的回文串，然后在根据起始日期和终止日期进行判断
from datetime import datetime, timedelta
a = int(input())
b = int(input())
t1 = datetime(1200, 1, 1)
t2 = datetime(1200, 12, 31)
v = []
while t1 <= t2:
s = t1.strftime("%Y%m%d")
p = s[4:][::-1] + s[4:]
v.append(int(p))
t1 = t1 + timedelta(days = 1)
ans = 0
for x in v:
if a <= x <= b:
ans += 1
print(ans)
