¿Cuando es su fiesta de cumpleaños?
-You need to know the days of the week.
Monday is lunes
Tuesday is martes
Wednesday is miercoles
Thursday is jueves
Friday is viernes
Saturday is sábado
Sunday is domingo
P.S. - In the Spanish calendar, the week begins on Monday, unlike in the traditional English calendar that starts on Sunday.
*Both walk into scene*
Anna - "¡Hola Daniel!
Daniel - "Hola Allen, cuando es su fiesta de cumpleaños?”
Anna - "Mi fiesta de cumpleaños es el sábado"
Daniel - "Gracias!"
Anna - "De nada!"
