From the book

The descent starts on 28 June 1863, at 1:13 in the afternoon, as soon as the shadow has shown the way. Their way out is the eruption that throws them onto Stromboli. Two days after that, on 31 August, a boat takes them to Messina, so they come out around 29 August: about two months under the ground.

Most of that is walking in the dark, through lava galleries and down shafts. On 7 August they are thirty leagues down. Soon after, Axel gets lost. Only on 13 August do they push off on the raft across the Lidenbrock Sea, and the storm and the eruption take the rest of the month.

The whole adventure is longer. It starts on Sunday 24 May 1863, when the professor finds the runes in Hamburg, and ends on 9 September, back home. At the harbour on Stromboli Hans is paid for his thirteenth week of work.
