How long it takes to dig a bunker by hand

[.*my*.]

I calculated how much ground you have to dig to make a bunker in 6 months.

If you want to make a small room (table, two chairs, bed) you would have to move 70 kgs (about 10 full buckets of soil) a day.

If you can manage that then you got yourself a bunker in 6 months.
