Start day 0 is the first day of the project. Bars are drawn to scale, so overlap on screen is genuine overlap on site.
The usual trick is a stacked bar chart where the first series is the start offset, made invisible, and the second is the duration. It works, but it breaks every time you insert a task, which is why most people rebuild it rather than maintain it.
The longest chain of dependent tasks. Every task on it delays the finish date one for one if it slips, and every task off it has slack. A bar chart alone cannot tell you which is which; you need the dependencies between tasks.
Decide once and be consistent. Working days are more useful for planning crews, calendar days for communicating dates to a client. Mixing them in one chart is how a plan quietly gains a week.
