My bad. I read 'setecientos' as 17, not 700.
Why's "mil needed
One thousand seventeen hundred twenty
Setecientos vs the suggested diecesiente, why!?
Because while it's pronounced 'seventeen twenty', in reality, it's 1000 +700+20, which is how it needs to be written.
I wanna say I've done this at least 8 times and forget "mil, lol
El año mil setecientos veinte.
