I was wondering if zero is an even number, or it depends on situation?

Even numbers(n) are often defined by the equation [itex]n=2k\;\;\;\; n\in\mathbb{Z}[/itex]. So, yes, zero is an even number.
 
Conversely, an even number is one that is evenly divisible by 2: there is no remainder. Since 0/2= 0, yes, 0 is an even number.

Shouldn't it be [itex]k \in \mathbb{Z}[/itex] ?
 
Yes. Probably a typo.
 
Indeed, well spotted cepheid.
