Well, you are also calculating leap, and allowing for the 100 year mark, and you have month scaled from 1 rather than 0. So the comparision is not quite fair. It also requires generating object code for various machines :-) However I suspect that mine will be more understandable. :-)

This will work for quite longer period:
u8 leap_year(u16 year) { u16 utmp; u8 leap = 0;
if(!(year & 0x03)) { utmp = (u16)((((u32)year)*41943)>>16); utmp++;
if(!(utmp&0x3E)) { if(!(utmp&0xC0)) leap = 1; else leap = 0; } else leap = 1; }
return leap; }

Don't forget that the clock changes by one hour twice a year for summertime...

This is intended to be my personal opinion which may,

And that for the southern hemisphere summer straddles the year-end.
