The difference between its and it’s
TLDR: Its is reserved for the possessive of ‘it’, whereas it’s is the contraction of ‘it is’.

These two are definitely one of the most commonly confused pairs of words in the English language.
I remember, back in primary school (for non-Australians, that’s from the ages of six to twelve), when I first learnt that its was not the same as it’s, I was very confused and got them mixed up for ages. I argued with my teachers, insisting that the possessive should be more important than the contraction and should, therefore, be able to have an apostrophe, or else they should both have the apostrophe! But I was just one voice in the stifling mire that is the English language and, consequently, my crusade ended soon afterwards and I decided to just learn the rule instead of fighting against it.
So here it is in all its confusing glory.

I still think it’s a stupid rule, though.
