So much depends on the groundwater temperature for me. I don't get hot water outside, just hose water, so I have to heat my strike water with my kettle. Usually I do this while I weigh and mill my grain and gather and prepare everything else. But sometimes it takes well over an hour (it takes a long time to get 40ยบ water up to ~170. So that starting point is 30-90 mins for everything up to mash-in, this is followed by 60 mins to mash, then I run off the first runnings into the kettle and start heating the first runnings while I batch sparge. From the end of mash till boiling usually takes 30 mins. I do 90-min boils about half the time now, and the rest of the time I do 60 min boils, so 60-90 mins for boil. If it's not a hoppy style, chilling wort takes 20-90 minutes, depending on the groundwater temperature. If it is a hoppy style, there will be 30-90 mins of hop standing, often in two stages (flame-out to ~180, then chilled down to >150 and another 30 minutes). Filling the fermenters and cleaning the kettle will be another 20-45 minutes.
So this can be an absolute minimum of 2 hours 40 minutes (very rare) to a max of 7 hours for that 96% pilsner malt session IPA in July.
