FF14 encyclopedia? Information needed.

[Sounsyy]

Can anyone help find information like this?

This older post of mine covers the lore behind units of measurement and time, including days of the week and the order of the years.
Anonymoose's Raimdelle Codex Alces provides a great beastiary inspired by the in-universe Raimdelle Codex.
Tinolqa created a similarly excellent compilation of Eorzea's flora in Botanica Eorzea.

So basically the old timekeeping standards from 1.0 are no longer adhered to by any ingame dialogue, nor are they mentioned in the Encyclopædia Eorzea (as far as I can find). If they came out and retconned them altogether it wouldn't really surprise me.

Considering we only got affirmation on the names of the days of the week at the 2014 Fanfest, I seriously doubt its "retconned" even if it's not as prominently mentioned as it was in 1.0. There's a lot of 1.0 flavor that just doesn't get mentioned frequently in ARR for whatever reason.

Yes! The days of the week definitely have names. Because the game was based off of themes that we had in Final Fantasy XI—the main lore guy was Kenichi Iwao, who worked on XI, and I had also worked on XI, and then we came on and started collaborating for XIV—and, again, it’s a new world, but we do want to, like with all Final Fantasy games, take stuff from previous Final Fantasies, and that’s one of the things that we wanted to take, because it was such a good system. In Final Fantasy XI, you had your elements, and because we have those same types of elements in XIV, we wanted to do the same thing—so you have your Watersday and your Firesday and you have your Windsday.
