As I said long ago, Punisher S2 - September 2017, JJ S3 - Feb./March 2018.
These are my arguments:
Punisher:
- 1 season ends in December 2016.
- Billy was in coma 6 weeks, he had 6 months therapy with doctor Dumont. So he was in coma to the end of January or beginning of February + 6 months = August at least. We can assume that the therapy didn't start right after he woke up. just a little later.
- In Beth's house her son is watching KHL - russian hockey league. It started on August 21 2017.
- Agent Medani was shot on December 2016 roku and we can see that one year passed since then. I think we shouldn't understand it literally, in fact only about 9 months passed.
- In one of the last episodes we can see doctor Dumond's passport with date of issue September 15 2017.
- Weather seems to be late Summer or early Autumn.
JJ:
- 1 year after season 2 (doesn't have to be exactly 1 year)
- Mother's Day in 6 months: 13th May (again, doesn't have to be exactly 6 months)
- Danny Rand is not in NY
- weather fits, not too warm, not too cold
