When making a website the website usually could be done in a week to going a full month.This depends on if lets say you have a client who owns a restaurant and needs a website improvement and fix-up. What that will usually take is a week or two when your trying to gather information to make websites better and using your own knowledge.Some people know what to do write off the bat when maybe they don’t have a website or its really bad, this comes with experience and knowing what to in these situations. usually the client will give you a due date to get it done and you should have it done by then or if your experienced you can just say ok ill tell you when the website gets started and when your in the end.
