My code:

#include <stdio.h>

void printdw(int* f1, int *f3, int d, int dd, int lim)
{
    int f2=0;
    if (d==1 || *f1==1)
    {
        if (dd==d) {printf(" [%2d]", d); f2=1;}
        else {printf("  %2d", d);}
        *f1=1;
    }
    else
    {
        if (dd==d) {printf("      [%2d]", d); f2=1; *f1=1;}
        else {printf("       %2d", d);}
    }
    for(d+=7; d<=lim; d+=7)
    {
        if (f2==1) {printf("  %2d", d); f2=0;}
        else
        {
            if(d==dd) {printf("  [%2d]", d); f2=1;}
            else printf("   %2d", d);
        }
    }
    if (d==lim+7)
        *f3=1;
    if(d<lim+7 && *f3) { if (!f2) printf("     "); else printf("    ");}
    printf("\n");
}

int main()
{
    int dd, mm, yy, dw, lim, f1, f2, f3, d;
    scanf("%d %d %d", &dd, &mm, &yy);
    dw=(6+yy-1600+((yy-1)/4-399)-((yy-1)/100-15)+((yy-1)/400-3))%7;
    if (mm==5) dw++;
    if (mm==8) dw+=2;
    if (mm==2 || mm==3 || mm==11) dw+=3;
    if (mm==6) dw+=4;
    if (mm==9 || mm==12) dw+=5;
    if (mm==4 || mm==7) dw+=6;
    if (mm>2) { if (!(yy%4)) dw++; if (!(yy%100)) dw--; if (!(yy%400)) dw++;}
    dw%=7;
    if (mm==1 || mm==3 || mm==5 || mm==7 || mm==8 || mm==10 || mm==12) lim=31;
    else
    {
        if (mm!=2) lim=30;
        else {if (yy%4 ||(!(yy%100) && yy%400)) lim=28; else lim=29;}
    }
    f1=0; f3=0;
    printf("mon"); d=(8-dw)%7+1;
    printdw(&f1, &f3, d, dd, lim);
    printf("tue"); d=(d+7)%7+1;
    printdw(&f1, &f3, d, dd, lim);
    printf("wed"); d=(d+7)%7+1;
    printdw(&f1, &f3, d, dd, lim);
    printf("thu"); d=(d+7)%7+1;
    printdw(&f1, &f3, d, dd, lim);
    printf("fri"); d=(d+7)%7+1;
    printdw(&f1, &f3, d, dd, lim);
    printf("sat"); d=(d+7)%7+1;
    printdw(&f1, &f3, d, dd, lim);
    printf("sun"); d=(d+7)%7+1;
    printdw(&f1, &f3, d, dd, lim);
}

Please! help to find mistake!
