How do we read the year in a date? how do we speak it?

Bonjour Jose !

There are two ways to say a year in French:
- you either read it as a normal number:
1820 = mille huit cent vingt (one thousand eight hundred and twenty)
- or you divide in the middle:
1820 = dix-huit *cent* vingt (eighteen hundred twenty)

I hope that's helpful!
À bientôt !
