Calender or Calendar: Which Spelling Is Correct?

Have you ever typed calender into Google, only to wonder if it should be calendar instead? You’re not alone. This is a very common spelling confusion, especially for students,

office workers, bloggers, and anyone who writes emails or documents regularly. Both words look almost identical, sound the same, and are often used in similar contexts—yet they do not mean the same thing.

People usually search for “calender or calendar” because they want a quick answer: Which one is correct? The confusion grows because spellcheck tools sometimes don’t clearly explain the difference,

and in spoken English, you can’t hear any distinction at all. Add British vs American English into the mix, and things feel even more confusing.

This article solves that confusion once and for all. You’ll learn the correct spelling, the real meaning of each word, their origins, and how to use them properly in everyday writing.

By the end, you’ll know exactly which word to choose—whether you’re writing a professional email, a blog post, or a formal document.

Calender or Calendar – Quick Answer

Calendar is the correct word when you mean a system for organizing days, weeks, and months.

Calender is a different word with a technical meaning related to pressing or smoothing fabric or paper.

Examples:

✅ Please check the meeting date on the calendar.
❌ Please check the meeting date on the calender (wrong).
✅ The fabric was passed through a calender machine.

👉 In 99% of daily writing, you need “calendar,” not “calender.”

The Origin of Calender or Calendar

The word calendar comes from the Latin word calendae, which referred to the first day of the month in ancient Rome. Over time, this evolved into the idea of tracking days and months.

Calender, on the other hand, comes from a different root. It entered English through French and refers to a machine or process used in textile and paper industries. A calender machine uses rollers to smooth or glaze materials.

Why the spelling confusion exists:

Both words share similar pronunciation.
Only one letter (“a” vs “e”) changes the meaning.
Most people rarely see calender used outside technical fields.

British English vs American English Spelling

Unlike many words (such as colour/color or organise/organize), calendar is spelled the same in both British and American English.
