What language was the calendar in? That's a first step to get the latitude.
Was the time of sunrise/sunset by day or by month average?
Was the time midnight-to-sunrise and midnight-to-sunset equal for each
measurement? That would indicate if the calendar was using solar or mean time.
N.B. in 1783, France was still using solar time (or so I think) while Britain
had, by then, generally shifted to local mean time - the transition was slow.
An interesting little problem. By 1793, the knowledge of astronomy was very
advanced in many European countries.
Let me know if you want help with a number-crunch. I have all the necessary
routines in Python and could try every possible combination with little
difficulty....
