Current Events How Long Will the "War" Take (In World Time)?

[Dettles]

Marineford the War between The Whitebeard Pirates and the Marines took (In World Time) about 6-12 hours. Compared too that How Long will the "Wano War" take?
The Dual between the Whitebeard Pirates and the Roger Pirates took 6 days with at least one (Ceasefire/Break) during it.
With How many Zoan types the Beast Pirates' have, and there fast recovery times, having a drawn out battle could give the Beast Pirates a huge advantage. (Especially if the "Gifters also get a bit of a recovery boost), and a longer battle could give the rest of the Big Mom Pirates time to get to the Battlefield, now that they could have Perospero and Big Mom to help them.
With the Strawhat adventures they seem to go down relatively quickly once the Action starts.
All of Dressrosa took less than a Day.
the Battles in Alabasta took less than half a Day.
ect.
In World Time how long do you think the War will Last?

Since this is the Beast Pirates that we are talking about, the war would probably take like 2 or 3 days or even more.

Imo there is the possibility that it becomes sort of a campal war in Wano, in that case could become like 2-3 days. But really depends on how many of the Alliance heavy hitters will get injured and need medication before being back on the field (Luffy and Kidd for example).
Otherwise it will be a rush of only one night.
