In the series, the stay on the island lasts 6 years, 2 months and 19 days. In the novel, however, Crusoe remains on the island for about 28 years.
The time frame of the series has been slightly changed or "modernized" in comparison to the source novel. In the novel, Robinson begins the return journey from his island, on which he had lived for many years, on December 19, 1686, reaching England on June 11, 1687. In the series, he does not begin his voyage to leave England before September 1, 1690.
