Input: Question: Possible Duplicate: "Toward" or "towards"? Which is the correct usage? "Onwards" or "Onward" ? For example: I would be free any time Tuesday onward. vs I would be free any time Tuesday onwards. Or is both correct/wrong? The spell checker in my browser says onwards is wrong but I've heard people using it. (p.s: Sorry if this question is redundant. I searched here but couldn't find a related question) 
Answer: Apparently, there is a slight difference, but only in British English: Note: In British English, 'onwards' is an adverb and 'onward' is an adjective. In American English and sometimes in formal British English, 'onward' may also be an adverb. So, depending on where you are, the difference maybe slight. However, they both mean the same thing practically, and most people will understand you if you use either anyways.
