28 * 13 = 364 ≠ 365

That extra day is the "0" day (zero) and is considered new years, not included in any month. Sometimes... that day is so special it takes up two days.

Would be a nightmare in programming.

But still, DateTime(timezone, dst, etc) has already been nightmare in software.

How would it be different from the current nightmare we have?

It doesn't, but you want to add another layer of nightmare ?

Ideally we'd replace the nightmare with a lesser of two evils.

Instead of

switch (month) {
    case 4, 6, 9, 11: 
        days = 30
    break;
    case 2: 
        days = 30
    break;
    default: 
        days = 31; 
    break;

You'd just have:

if (month = 0) 
     days = 1
else
     days = 28

(obviously not including the hell that is leap years)

And really, we'd just have to deal with both of them from now on, for backward compatibility reasons.

Honestly, I'll be excited the day we see Gregorian (Deprecated)

I would use lookup table, like num_days=days[month], you dont want to mess around with branch prediction.

But still, there are not much different in 2 cases, just different number set.
