When did the 18th century enlightenment start and when did it end?

Answer 1

The question concerns "the Age of Enlightenment", not the 18th century CE.
See

and the answer voted best to the question
"When did the enlightenment period start?".
"HRH Princess Deb" entered that answer, which I'll copy here:
"There is no consensus on when to date the start of the age of Enlightenment, and some scholars simply use the beginning of the eighteenth century or the middle of the seventeenth century as a default date. Other scholars use the beginning of the Napoleonic Wars (1804–15) as a convenient point in time with which to date the end of the Enlightenment. Still others describe the Enlightenment beginning in Britain's Glorious Revolution of 1688 and ending in the French Revolution of 1789. However, others also claim the Enlightenment ended with the death of Voltaire in 1778."
