Well, now you know why I suspect DPC messed up the timeline.
In EP7, Maya said the following to the MC.
Maya: "I could suck it up for four years and be done with it..."
Maya: "Three years if I study hard and take extra classes."
Maya: "After that, it would be easier to break free."
2020-2017=3
Maya's calendar is too obvious a reference to this because DPC explicitly edited the calendar for EP6 because the date in EP7 is back to 2017. This suggests so we could have full college time. The only problem is how DPC embedded this 3 year difference into the story. It can really only happen through three dings, but they can also be combined. Kinship, tragedy, and time jumps.
One can speculate actually also in such a way that the MC tells its history it year 2020.
