I think the N.O. calendar has things like today's Daily Dungeon, today's Bounty Hunter, and so on. In other words, stuff that a person (or bot) has to actually sign on to the game and spend turns to find out.
I like the idea of adding those things to KoLmafia's internal almanac - by harvesting it from the N.O. calendar, if they'd give us permission to do that.
But short of that, adding a link to the N.O. calendar is not a bad idea. I have to google it every time I think to look at it, and having a built-in link would make me look more often, probably.
