century year handling

[nickolas1]

Hi there,

the handling of century years seems to be not quite correct- they should only be leap years if they are divisible by 400, so 1900 and 2100 are not leap years, while 2000 is. I believe this could be fixed with a change like this to daysInMonth:

return (month === 2 && year % 4 === 0 && (year % 100 === 0 ? year % 400 === 0 : true)) ? 29 : days[month - 1];
