Objectives:
The objective of this program is to test your ability to perform Python arithmetic, input/output,
decision, and repetition statements.
Description:
The following algorithm will calculate the date of Easter for any year in the twentieth or twenty-
first centuries for Western dates. Valid years are 1900 to 2099. Have the user input a positive
year.
Subtract 1900 from the user input year and call the difference valueD.
Divide valueD by 19 and call the remainder valueR.
Divide (7 * valueR + 1) by 19. Discard the remainder and call the quotient valueP.
Divide (11 * valueR + 4 valueP) by 29 and call the remainder valueS.
Divide valueD by 4. Discard the remainder and call the quotient valueQ.
Divide (valueD + valueQ + 31 valueS) by 7 and call the remainder valueT.
Easter is on (25 valueS valueT). If this result is greater than zero, Easter for that year occurs in
April on that date.
If the result is zero or negative Easter for that year falls in March. If the result is 0, Easter for
that year falls on March 31 (31 0). If the result is 1, Easter occurs on March 30 (31 1). If the
result is 2, Easter occurs on March 29 (31 2), etc. (Hint: What happens when you subtract a
negative number (-1) from a number as in (31 (-1))?)
Assignment:
Write a program, name it Easter.py that will ask the user to input a year and calculate the date of
Easter for that year. You may need to verify your programs accuracy by doing each step by hand
then check your programs values at that point. Your program should produce a single line of
output of the form:
(Western) Easter Sunday - 28 March, 1948.
Assume the user always inputs a valid year.
Once your program outputs, it should loop back to the beginning and ask the user for another
year. If the user inputs a negative year, stop the program, and say Bye.
