📅 Calender or Calendar: Which Spelling Is Correct?

Calendar is the correct spelling when referring to a system for organizing days, weeks, months, and years. It is also the word used for a schedule that lists appointments, meetings, holidays, and other important events.

Calender is a real English word, but it has a different and specialized meaning. It refers to a machine or process used to press, smooth, or finish materials such as paper, cloth, or rubber. Therefore, it is not an alternative spelling of calendar.

Quick answer: Use calendar when talking about dates and schedules. Use calender only when referring to the specialized manufacturing machine or process.
