{333} There are two clues to work with. In Robert Walton's fourth letter, dated August 5, we are told that the preceding Monday was July 31; and in Alphonse Frankenstein's letter to Victor (1.6.2) giving him the news of William's death, we are told that William died on Thursday, May 7.-- Leonard Wolf, The Essential Frankenstein (New York: Plume, 1993) -- from Appendix D, pp. 333-34.If we consult a perpetual calendar we learn that in the late eighteenth century:
{334} The question then is whether a single calendar can be created to accommodate the certain dates with which we started. Since we know that four years have elapsed between the murder of William and the time when Walton sees the creature on the Arctic ice, we should expect our extrapolation to carry us neatly from Thursday, May 7, 17--, to Monday, July 31, 17-- + 4. Sadly enough, that does not happen. There is no way to bring our two dates into a single calandar.

The events of the central narrative involving the De Laceys, their reading of Volney's Ruins of Empire (pub. 1789), and the absence of hostilities across the novel's European landscape might suggest a timeframe in the early 1790s, after the fall of the Bastille but before Europe was engulfed in warfare in 1793.
