Calendar is the correct spelling. Calender is a different word used in manufacturing. For example, you write “Check your calendar for the meeting,” not “Check your calender.”
A few years ago, I was proofreading a student’s essay when I noticed something odd. She had written, “I marked the date on my calender.” At first glance, it looked fine. Many people make the same mistake.
Have you ever typed calender instead of calendar and wondered if it was actually wrong? You’re not alone. This is one of those spelling pairs that confuses students, writers, and even professionals.
The confusion happens because the two words look almost identical. Yet they have very different meanings. One is something most of us use every day. The other belongs to a completely different industry.
If you’ve ever searched for “calendar or calender,” you’re probably trying to find out which spelling is correct and when each word should be used. By the end of this guide, you’ll know the difference, avoid common mistakes, and use the right word with confidence.
Calendar or Calender : Quick Answer
Calendar is the correct word when talking about dates, months, schedules, or events.
Calender is a real word, but it refers to a machine used to press, smooth, or finish materials such as paper, cloth, or plastic.

The Origin / Background of Calendar or Calender
The word calendar comes from the Latin word calendarium. It was related to accounting records and the first day of the month in ancient Rome. Over time, the meaning evolved into the system we use today to organize days, weeks, and months.
The word calender has a different history. It comes from languages linked to textile and paper manufacturing. A calender is a machine that presses materials to make them smooth or glossy.
The confusion exists because:
- Both words look very similar.
- They differ by only one letter.
- Most people rarely encounter the industrial word calender.
- Spellcheck may not always catch the mistake because both words are valid.
That is why many writers accidentally choose the wrong spelling.
