Many English learners, students, and even native speakers wonder whether the correct spelling is calendar or calender. Since the two words differ by only one letter, they are easy to confuse. However, only one spelling is correct when referring to a system for organizing days, weeks, and months. The correct spelling is calendar, while calender is usually a spelling mistake in modern English.
The word calendar is used every day in homes, schools, offices, businesses, smartphones, and digital apps. It helps us organize appointments, meetings, holidays, birthdays, and important events. Whether you’re talking about a wall calendar, an online calendar, or a work schedule, calendar is the correct spelling. The word is spelled the same in both American English and British English, so there is no regional variation.
Many people mistakenly write calender because the pronunciation is similar and the words look almost identical. In fact, calender is a rare technical term referring to a machine used in paper and textile manufacturing, not a date planner. Understanding the difference between these words will help you avoid a common spelling mistake and improve your English writing.
