Well, the time for self-editing a novel can be quite different for everyone. If it's a short and straightforward novel, it might take you a month or so. But for a longer, more complex one, it could easily take three months or more. Your attention to detail and how much revision you want to do also play a role.
Self-editing a novel can take a significant amount of time. It often depends on factors like the quality of your initial draft, your experience in editing, and how thorough you want to be. Sometimes, it can take up to half a year to get it just right.
It really varies. It could take anywhere from a few weeks to several months, depending on the length and complexity of the novel and your editing skills.
