I think this is mostly a US thing. Why use yearly salary? You’re not paid once a year, are you? Most likely once a month. Referencing monthly salary makes much more sense.
“I’m making 50k”. Great, now I have to guess - dollars? Monthly? Yearly? If yearly then what’s the monthly paycheck? Net? Gross?
It’s pretty standard in Europe too. It’s what you see when filling your taxes, but very often people have bonuses, over-time, 13rd month and other things making monthly pay not relevant
The Thirturd month is my favorite month of the year
Stupid Smarch weather
wait till you hear that in Italy we have 14
but only if you are lucky and it’s heavily taxed.
