I am getting this really bizarre error. In cell A1 I have 21/02/1971 (Brazilian-style date), in A2 I have
=today()-A1. I receive the following error:
#VALUE! Error: Function MINUS parameter 2 expects number values. But '21/02/1971' is text and cannot be coerced to a number.
The weird thing is: if I change the date, say, to 22/02/1971, or 21/03/1971, or 21/02/1972 or any combination like that, everything works fine and the formula actually calculates what's supposed to. Any clues? Already tried disabling cookies, cache, restarted browser, tried different browser and computer, all the basic stuff.
