Re: timeline question
It could very well be the next mission right after Obito's death that Rin/Kakashi took on. (Also depending on if you believe it was a mission and your own theory).

As for the headband, I do think a lot of people are blowing this a little bit out of proportion because there are plenty of times Kakashi did not fight with his headband within the series. Anyway to answer your question to the best of my knowledge, Kakashi takes off his headband right after his regular eye gets cut. Even after Rin transplants the Sharingan in Kakashi's Eye Socket and then he goes on to fight Kakko, he still does not have the Konoha Headband and if memory serves me correctly it was because Rin had originally bandaged most of his head and then most of the bandanges remained on after the Sharingan was implanted, but no headband, so I would say this had to have happened maybe 2-6 months after since the Kannabi-Bridge Incident turned the tide of the War heavily into Konoha's favor.
Link is self-explanatory, hope my post helped.
Hahaha, yeah I agree completely. I mean the only thing that grew on Obito was his Hair, maybe Madara stocked up on Rogaine, but otherwise I agree none of the 3 look more than 6-8 months older MAX.
