This spelling variation appears in literature, everyday writing, newspapers, and academic texts. Using the correct form helps maintain clarity and consistency. Understanding when to use nighttime and night-time is important for academic work, professional writing, and casual communication. In this article, we explain the meaning, spelling differences, regional preferences, common mistakes, and useful examples so you can confidently choose the correct form in any context.
What Does “Nighttime vs Night-Time” Mean?
Both nighttime and night-time refer to the period of the day when it is night. This usually means the hours of darkness between sunset and sunrise. The meaning of the word does not change with spelling. The difference is mainly regional and stylistic. Nighttime and night-time are used in writing related to weather, sleep, travel, schedules, and everyday routines.
Examples:

In both examples, the meaning remains the same. Only the spelling changes depending on style and regional preference.
Spelling History and Development
Nighttime and night-time both come from the words night and time. Over time, the hyphen in night-time became less common in American English, and nighttime became the standard spelling. In British English, night-time continued to be used more often, though nighttime also appears in modern writing. The change mirrors a general trend in English where compound words often lose hyphens and become single words.
Other examples of hyphens disappearing include:
- today (formerly to-day)
- tonight (formerly to-night)
- tomorrow (formerly to-morrow)
These examples show how English simplifies spellings over time.
