Cultural Tip
In Spanish‑speaking countries, events are often announced with "es" + day of the week, and the masculine article "el" is always used before the day, even though the event itself may be feminine ("la fiesta"). Parties in many Hispanic cultures tend to start later in the evening, so you might also hear "La fiesta empieza a las ocho el viernes."
