im confused on saying 7:20 in spanish

PM? Son las siete y veinte de la noche.

AM? Son las siete y veinte de la mañana

I only use

Son las siete y veinte.

It is very unusual to use AM or PM coloquially (because you see if it is morning or evening time).

To say "7:20" in Spanish, you would typically use the phrase "siete y veinte." Here's how you can break it down:

1. Start with the word for "7," which is "siete."
2. Next, add the conjunction "y," which means "and."
3. Finally, include the word for "20," which is "veinte."

So when you put it all together, "7:20" in Spanish is "siete y veinte."
