The official Ballista matches are only held on 4 days of the week starting at 0:00. They last a full hour.
Windsday Earthsday Thundersday Darksday
This is semi interesting because it actually makes Day of the Week weapons, Avatar Weapons, and Staff/Obi combos really nasty. If anyone has ever used Shiva's Claws on Iceday, Garuda's Dagger on Windsday, or Titan's Cudgel on Earthsday you'll see a huge increase on the proc rate.
Garuda's Dagger is especially potent in Ballista during Windsday and provides multiple overlapping silence procs making it horribly nasty in a no-item Ballista.
Campaign Fortifications
I'm unsure if this is common for all Fortifications, but most of the Campaign Fortifications I've fought appear to face to the East. This is probably only something really useful for jobs that try to meet positional requirements when engaged.
THF - SA from the West to meet Sneak Attack reqs SAM - WS from the East to meet Overwhelm reqs NIN - WS from the West to meet Yonin reqs
Blessed Radiance
I tried to fish out a little more info for Blessed Radiance, the high-end NPC Weaponskill. In order to trigger the NPC WS both you and your NPC must be in red health.
Here are two other screenshots of my NPC using the Stoneskin aftereffect to tank.
