Hi there. I love what you've done and would like to try visualizing some of these in a 3D GEDCOM viewer I am working on https://github.com/mister-blanket/roots. I've tried using the periandi.ged file to test, but the very large gaps in some of the birth dates makes it difficult to view. From what I can tell, it seems you are using mostly Shire Reckoning, but for a few of the important hobbits are using TA Reckoning. Do you, by chance, have any version of the file which uses a single reckoning? If not, I might look into making one, I just thought I'd check first. Thanks for your hard work!
