Is zero even or odd? [duplicate]

$\begingroup$

This question is already answered on here. head over to that link.

I have been sitting here wondering if zero is even or odd and if it is even why is it even. I have no justification for why it is odd or even. Understanding that justification would be great.

It feels even, but no idea why.

Note that the number before any odd number is even. For example, five is odd, and so 4 is even.

Note that 1 is odd. Therefore, zero is even.
