Wrong year in category name?

Question

We have a category "Siege of Calais (1346)". Should it not be 1347?

Answer 1

Considering the timeframe of this particular siege, I would be inclined not to have a year/years in brackets

Comments

Problem is that there were later sieges of Calais.

Since the siege lasted 11 months, should it not be: "Siege of Calais (1346-1347)" ?

Mind that it must be a minus or hyphen between 1346 and 1347. en or em dashes are not allowed in category names.

That makes sense

Answer 2

The siege took place over two calendar years, so it should be "Siege of Calais (1346-1347)" or "Siege of Calais (1346-7)".
