Is 0 odd or even?

Zero is an even number.

An even number is a number that can be divided by 2 with no remainder.

0 ÷ 2 = 0

There's no remainder, so zero is even.

Like CPhill said, Wikipedia explains that zero is even.

Also, many other math resources say the same.

Even..........according to Wikipedia:

Zero is an even number. In other words, its parity—the quality of an integer being even or odd—is even. The simplest way to prove that zero is even is to check that it fits the definition of "even": it is an integer multiple of 2, specifically 0 × 2. As a result, zero shares all the properties that characterize even numbers: 0 is divisible by 2, 0 is neighbored on both sides by odd numbers, 0 is the sum of an integer (0) with itself, and a set of 0 objects can be split into two equal sets.

Thanks for all those links, ND....!!!
