If you’ve ever wondered whether to write mid-day or midday, you’re not alone. These two spellings often cause confusion because they look almost identical and refer to the same general time of day. However, one form is considered the standard spelling in modern English, while the other is much less common.
The good news is that the difference between mid-day and midday is mostly about spelling conventions rather than meaning. In this guide, you’ll learn which form is preferred, how each is used, examples, common mistakes, regional differences, and helpful tips to remember the correct spelling.
Quick Answer

- Both refer to the middle of the day, usually around noon.
- In most writing, midday is the recommended choice.
