You’re Not Alone
If you sometimes spell calendar as calender, you’re not alone. This is a common spelling mistake because both versions sound very similar when spoken. The good news is that the correct spelling, calendar, becomes easy to remember once you learn a simple spelling trick and practice it in a few everyday sentences.
Why This Mistake Happens

The spelling mistake happens because calendar and calender sound very similar when we say them aloud. Since the pronunciation does not clearly show the final vowel, it is easy to write the wrong ending.
Another reason is that -er is a very common ending in English words. When people spell calendar based on how the word sounds, they may automatically write calender instead of remembering the correct -ar ending.
The best way to avoid this mistake is to practice the correct spelling: c-a-l-e-n-d-a-r. A simple memory trick is to remember that calendar ends with dar, just like the last three letters in the correct spelling.
Word Origin
The word calendar comes from the Latin calendarium, meaning an account book or record of debts, and is related to Kalendae, the first day of the Roman month. It later passed through French before becoming the English word calendar we use today.
The Spelling Trick
A simple way to remember calendar is to break it into smaller parts: cal-en-dar. Focus on the ending dar, not der. When you see the word in your mind, picture a calendar with the final letters DAR clearly highlighted.
You can also remember the phrase “A calendar has dates” and connect the a in calendar with the a in dates. Practice writing calendar several times while saying each part aloud: cal-en-dar. This makes the correct spelling easier to recall.
