hihi! firstly, please aim to finish your fic by the deadline! we offer extensions because we understand that extenuating circumstances happen, or that people may have things to do outside of writing that means they need a bit of extra time to wrap up their fics after the deadline. this is why we do not offer extensions until much closer to the deadline - to make sure that everyone tries their best to finish the fic on time!! that being said, extensions start at a few days to a week depending on how long you need during the initial request, but it always varies from person to person. good luck! ^^
