C | Problema de calculare a datei Pastelui catolic

Salut, am un program care ar trebui sa calculeze data Pastelui catolic dupa citirea unui an. Am sa va postez cerinta si ce am incercat sa fac, nu imi iese bine data la unii ani, daca puteti sa ma ajutati va rog sa vedeti ce am facut gresit.


This program takes as command line a single integer value which represents a year and then computes and displays the Easter date for that year
The algorithm for computing the catholic Easter date is the following :
A = year mod 19
B = year mod 4
C = year mod 7
D = (19 * A + 24) mod 30
E = (2 * B + 4 * C + 6 * D + 5) mod 7 where mod is the remainder of the division of x to y.
Easter day is then(22 + E + D) March. Note that this formula can give a date from April if 22 + E + D > 31; also take this case into account!
The program will display the Easter date in the following way "The Easter day is 02 April " (use trailing zeros for the day if it is less than 10)

#include <stdio.h>
#include <stdlib.h>
int main() {
int Easter;
int x,y;
scanf("%i",&x);
int A,B,C,D,E;
A = x % 19;
B = x % 4;
C = x % 7;
D = (19 * A + 24) % 30;
E = (2 * B + 4 * C + 6 * D + 5) % 7;
Easter = (22 + E + D);
if(Easter <= 31)
{
if (Easter < 10)
printf("The Easter day is 0%i March", Easter);
else
printf("The Easter day is %i March", Easter);
}
else
{
y = Easter - 31;
if (y < 10)
printf("The Easter day is 0%i April", y);
else
printf("The Easter day is %i April", y);
}
return 0;
}

Multumesc anticipat!

Din ce vad, programul e corect.
Doar ca algoritmul e incomplet si limitat:

Quote

printf stie de leading zeros
printf("%02d\n",numar)
Tu trebuie sa determini in ce luna pica sarbatoarea.

sunt librarii cu care lucrezi cu date/datetime, ce faci tu se numeste reinventarea rotii.

Omul din greseli invata.

if (day > 31)
	{
		day-=31;
		sprintf(month,"%s","April");
	}
	printf ("%02d %s\n", day, month);

mai putine if-uri, mai putina bataie de cap
