Anyday or Any Day: Correct Meaning, Usage, and Examples 2026

Many English learners and even native speakers often feel confused about whether to write “anyday” or “any day.” At first glance, both look correct. However, only one form is grammatically accepted in standard English.

This confusion happens because English often combines words over time (like “everyday” vs “every day”). So, it’s natural to wonder if “anyday” follows the same pattern. However, the rules here are slightly different, and understanding them will improve your writing clarity.

Whether you follow British English (UK) or American English (US), knowing the correct form is important. It helps you write professionally, avoid mistakes in exams, and communicate clearly in emails, essays, and daily conversations.

Quick Answer

The correct form is “any day” (two words).

👉 “Any day” means any time or whenever possible.
❌ “Anyday” (one word) is not standard English and should be avoided in both UK and US writing.

Example:

✅ I can meet you any day next week.
❌ I can meet you anyday next week.
