Cultural Tip
In many Spanish‑speaking countries, especially in Spain, dinner is often eaten late (9‑10 p.m.) and people may stay up past midnight. Saying 'a medianoche' sounds a bit formal; native speakers more commonly say 'a las doce' or simply 'a medianoche' when they want to stress the exact hour.
