I have been looking for a family tree program that I can use to track many families in a fictional (fantasy) world, but always get hung up when it comes to dates. My world calendar is similar, but just different enough to make using the real calendar challenging.
I came upon Family Echo as a nice, basic heredity program, but wonder if there is a way to hack the interface to include months with more days or to rename months as if they were another language?
Or, if anyone can suggest another engine offline or online that can do this I'd be obliged.
