The Bad Batch arc is about 6 months prior to RotS, and is a part of the Outer Arun Sieges. That’s why Parme still isn’t really showing in the hologram, though she knows and was about to tell Anakin.
The Trace/Rafa arc is about 2 1/2 to 3 months before that, when Anakin leaves for the Outer Rim sieges.
So basically most of TCW stories are crammed into three years or so of the clone war, while there’s roughly six months (or more?) of untold stories predating the events shown in season 1 (though technically it was originally shown in the Tartakovsky series before it was de-canonized) and about six months or so between the start and finish of TCW season 7?
For context I’m referring to Anakin being knighted and having time to grow his long hair (plus gain his scar) when I’m talking about pre season 1 events. Maybe six months is a bit of a stretch, but it would have to at the very least be a couple of months?
Different people will tell you different timeframes of The Clone Wars, what’s generally accepted by people working on those shows is that it’s roughly five years. This allows Ashoka to grow over the course of the series from roughly 12 to roughly 17. As far as the timeframe prior to Ahsoka’s arrival, be that “pre-Season 1” or the parts of Genndy’s series that haven’t been contradicted, is less established, and I’d guess was only a couple of months.
Right, though for some weird reason I always thought the clone war was canonically four years long. Maybe that’s a Legends thing? Five years makes a fair bit more sense though, but I still find it odd that Anakin was knighted, scarred by (presumably) Ventress, and grew his hair to shoulder length in just a couple of months all between AOTC and TCW season 1.
I still think it’s funny how Lucasfilm keeps expanding everything Filoni-related, but keep ignoring the pre TCW season 1 events, leaving both Ventress’ and Grievous’s first appearances as untold stories. Though I personally find a certain charm in the absolute canonical mess that is the connection between the two clone wars series and how Filoni’s series (most of it anyway) technically exist in both canons.
