That's all well and good, but I was hoping to have something more like a dating system that we could use to annotate IC posts for a more consistent series of events at some point going on (or at least circa dates). If we could get something preferably close to a planetary circuit of the sun, we can have a better idea as players of when a post is taking place in canon.

Something like Inundation 401 + 20 days might be a bit unwieldy.

Point is, we might have systems, but we haven't actually had a sheet explaining how these systems work.
