I was reading Writing Magazine, and thoughtful writer Wendy Clarke had sent a letter with details of a story timeline Excel document, set up by her husband. If you’re writing a book that involves any kind of time shifts, I can recommend it. I’ve already downloaded a copy from Wendy’s blog, and inserted my main characters’ birth years; their ages are automatically calculated on the timeline. Lists of British monarchs, Prime Ministers and some key events through the years is a lovely additional detail, and fills in the plentiful gaps in my knowledge. Thanks to Wendy for sharing.
