Thanks for replying!
I went back to volume 3 and as it turns out, I totally missed this line:
"Safu left her store, and Karan had followed shortly afterwards. What she witnessed was the kidnapping of Safu by Security Bureau officials. It had already been three days since then."
volume 3, chapter 2And you're right, it does say the Holy Celebration is the week after in that same chapter.
So then there's a week between Safu's kidnapping and the Manhunt? Which does collide nicely with your timeline. But. A week.
What. I need to readjust my entire view. XD; (this is good news for my fanfic though, but still. I thought they had more time in the West Block together so now I'm sad.)
The spring and 2017 thing still doesn't make sense though... Unless No. 6 uses years differently or something, which is theoretically possible (e.g. December would be what we call February, or the new year starts in March or something), orrrr that was just a mistake/artistic license for symbolism.
