✕Common Mistakes

Cancela al menos 24 hora antes.
The noun must agree in number with the numeral; use the plural “horas”.
Cancela al menos 24 horas antes de.
Adding “de” after “antes” is redundant here; the phrase already implies “before the appointment”.
Cancela al menos 24 horas menos.
Do not split the fixed expression; it must stay together as “al menos”.

Cultural Tip

In most Spanish‑speaking countries, service providers set a 24‑hour cancellation window to protect their schedule. Using the informal imperative (cancela) is appropriate when speaking to a customer in a friendly tone; in formal contexts you would say “cancele”. Also, “antes” works without “de” because the reference point (the appointment) is already understood.
