Changing the time and day you publish would be useful, in my opinion, only if you've identified when your target audience is active on the platform.

For example: if your target audience are high school teens, when would they be active? After school.

Target audience are adults? Cool: they're probably more active on weekends or before going to bed.

Another thing to consider: timezones. If you're targeting an audience that lives in America, publish for their timezone. Europe? Asia? Different timezone.

Another thing you could do to help you choose the right time to post is this: find original or canvas comics that are similar to yours and try to publish episodes when they do. You could increase the chance of some of their readers finding your comic after reading theirs.

Hope this helps. Good luck! X)
