Printing Easter date occurrences

[samsonite]

My last trial! Please, may I have help? Thank you

# ---------- ea2.py ---------------

from datetime import date

def calc_easter(self, year):
    "Returns Easter as a date object."
    a = year % 19
    b = year // 100
    c = year % 100
    d = (19 * a + b - b // 4 - ((b - (b + 8) // 25 + 1) // 3) + 15) % 30
    e = (32 + 2 * (b % 4) + 2 * (c // 4) - d - (c % 4)) % 7
    f = d + e - 7 * ((a + 11 * d + 22 * e) // 451) + 114
    month = f // 31
    day = f % 31 + 1    
    return date(year, month, day)

start_interval= 1950
end_interval= 1960

r = range(start_interval, end_interval+1)
for n in r:
	s=calc_easter(date, n)
	print(date.month)  # my intention is to extract the month number (3 or 4),
	                   # same story for the day
                       # and then if condition will solve the matter
