'''
输入某年某月某日，判断这一天是这一年的第几天？
思考：之前的月份天数的累加，先对年作出判断，再对月做判断
'''

year = input("请输入年")
month = input("请输入月")
day = input("请输入天")
year = int(year)
month = int(month)
day = int(day)
list1 = [31,28,31,30,31,30,31,31,30,31,30,31]
total = day
while month -1 >0:
	total += list1[month-2]
	month = month-1
# 能被400整除的，或者不能被100整除而能被4整除的年就是闰年
if year%400 == 0 or (year%4 == 0 and year%100 != 0):
	if month > 2:
		total += 1
print(total)
