calendarizar

To schedule or put something on a calendar — a somewhat formal, businesslike verb used for planning events, meetings, or academic terms. Common in institutional and workplace Spanish, especially in Latin America.

• Calendarizaron las reuniones para todo el trimestre. — They scheduled the meetings for the whole quarter.
• El colegio ya calendarizó los exámenes finales. — The school has already scheduled the final exams.
• Necesitamos calendarizar las entregas del proyecto. — We need to schedule the project deliverables.

This verb leans formal/institutional — in casual conversation, programar or planear a specific date is far more natural than calendarizar, which can sound stiff outside office or academic contexts.

Often confused with programar.
