Thanks for the link, I'll check it out when I get a chance.
I find spreadsheets very cumbersome for this sort of thing. I've been using tables inside LibreOffice Writer documents, that's also far from ideal but I've managed to make it work so far.
My current big project (which has spent far too much time on hold while I try to keep up with work
), has a back story reaching over thousands of years. I've been trying to work with a Wiki ... but that is proving to be less than ideal too (I spend too much time on the mechanics of keeping all the pieces in sync - it's distracting).
I've looked at other tools that are supposed to have timelines, but none of them worked well for what I wanted.
I need flexibility. In previous books I've been working at month scales for some parts of the book (actually over a century if you include the back story, which my timeline did) and down to minutes for others parts, trying to keep track of who was where exactly when. And even though the book never actual says when it happened, the timeline that grew as I wrote the story had everything down to specific dates so that I could keep track of moon phase, sunset and sunrise times and so on. For example, with the fire scene at the end of one book I wanted the timing synchronised right with sunset and city traffic to have the events and effects come out as I wanted. (Okay, so I also tend to be a bit obsessive, but that's my problem and I'm working on it ... obsessively
).
If the software is any good, I will consider the price to be very cheap.
