The Origin of Calendar or Calender
Although these words look alike, they come from different historical backgrounds.
Origin of Calendar
The word calendar comes from the Latin word kalendarium, which was connected to Kalends, the first day of the Roman month. Ancient Romans used this word for records of dates, payments, and important events.
Over hundreds of years, the spelling became calendar, which is now used worldwide to describe systems that organize days, weeks, months, and years.
Examples include:
- Wall calendar
- Digital calendar
- School calendar
- Event calendar
- Holiday calendar
Origin of Calender
The word calender comes from the French word calandre, which referred to a machine that pressed cloth.
Today, a calender is:
- A machine used in factories
- A process that smooths paper
- Equipment used to finish textiles
- Machinery that presses plastic or rubber
Because this meaning is limited to manufacturing, many English learners never encounter it.
British English vs American English Spelling
Unlike many English words, calendar is spelled the same in both British and American English.
| Feature | British English | American English |
|---|---|---|
| Correct spelling for dates | Calendar | Calendar |
| Used in schools | Yes | Yes |

| Alternative spelling | None | None |
Examples
British English

American English
