If you’ve ever paused while writing and wondered whether it’s anyday or any day, you’re definitely not alone. This is one of those small grammar details that trips up even fluent English speakers.
The short answer? The correct standard form is “any day” (two words). But there are some important nuances depending on how you’re using it.
Let’s break it down in a simple, practical way so you never get confused again.
Is Anyday One Word?
One of the most common questions is: is anyday one word?
The answer is no—at least not in standard English.
- “anyday” (one word) → generally incorrect in formal writing
- “any day” (two words) → correct standard usage
While “anyday” sometimes appears in casual texting or branding, it is not accepted as standard grammar in dictionaries or formal writing systems.
Any Day vs Anyday: What’s the Difference?
Let’s clear up any day vs anyday in a simple way.
Any Day (Correct Form)
Used when referring to:
- A general day in the future or present
- Flexibility in time
- Non-specific days
Example:
- “You can call me any day this week.”
Anyday (Incorrect in formal English)
- Not standard grammar
- Sometimes used informally or stylistically
- Appears in brand names or slang contexts
So in proper writing, any day is always preferred.
Anyday vs Any Day: Why the Confusion Exists
The confusion around anyday vs any day comes from how spoken English sounds.
When we speak quickly, “any day” often sounds like one blended word. Over time, this leads to misspellings in casual writing.
Common reasons people get it wrong:
- Fast texting and autocorrect habits
- Influence of social media slang
- Brand names using “Anyday” for style
- Mishearing spoken language
But in grammar rules, separation matters.
When to Use “Any Day” in Sentences
Understanding usage is more important than just spelling.
Time flexibility

Uncertainty

General reference

In all of these, any day refers to a non-specific time.
When “Anyday” Might Appear (But Should Be Avoided)
Even though is anyday one word is a common search, the reality is:
It may appear in:
- Brand names
- Usernames or handles
- Informal slang online
But in academic, professional, or SEO writing:
- It should be avoided
- “Any day” is always safer and correct
Why “Any Day” Is the Correct Grammar Choice

- “Day” = noun
Together, they form a noun phrase:
“any + noun” → always written as two words in standard English
This is why similar phrases follow the same rule:
- any time
- any place
- any person
