App works very well and visually nice too, as long as you want to use it with our existing timeline. It would instantly increase its possible audience (think fiction writers) if it would allow custom dates. For example, I’m trying to gather data on a fictional story that not only uses one set of dates (such as BC/AC) but has 4 different (sequential) calendars, each starting with a year 1. Converting all these fictional dates to the existing model is very cumbersome.

[Update] Received a good developers response. Thank you for that idea! Unfortunately they are not parallel timelines but still linear. Looking forward to future versions of this app.

**Developer response:** Thank you, that is a really useful suggestion! Custom date systems are not in the app today, and you are right that converting fictional dates by hand is tedious… I have already added your idea to my list for a future update.
As a workaround it might help to put each of the four calendars in its own collection. The app shows collections side by side, so at least the eras would stay visually separated. Thanks again for the detailed feedback.
