In standard formal English, at any time is the preferred form.
More examples

- The rules may change at any time.

🔍 Anytime vs. At Any Time
These forms can have nearly the same meaning in many sentences.
Compare:
You can call me anytime.
You can call me at any time.
Both mean that you can call whenever you want.
However, at any time often sounds more formal or deliberate, while anytime sounds more natural in casual conversation.
| Anytime | At any time |
|---|---|
| More conversational | More formal/neutral |
| Adverb | Prepositional phrase |
| Call me anytime. | Call me at any time. |
| Common in casual writing | Common in formal writing |
💬 Anytime in Casual English

You may see it in:
- Text messages
- Emails
- Conversations
- Social media posts
- Friendly invitations
- Informal instructions
Examples
Text me anytime.
You can come over anytime.
Let me know anytime.
Call me anytime you need help.
These sentences sound natural and conversational.
🎓 Any Time in Formal English
Formal writing often favors at any time when the meaning is “whenever.”
For example:
Customers may cancel their subscription at any time.
This sounds appropriate for:
- Terms and conditions
- Business documents
- Policies
- Legal writing
- Official notices
- Academic or professional writing
However, anytime is not automatically incorrect in formal writing. The choice depends on the sentence and style.
🚫 Common Mistakes With Anytime and Any Time
Understanding a few common errors can help you avoid confusion.
Mistake 1: Using “anytime” as a noun
Incorrect:
I don’t have anytime today.
Better:
I don’t have any time today.
Here, time acts as a noun, so use two words.
Mistake 2: Writing “at anytime”
Incorrect:
You can cancel at anytime.
Correct:
You can cancel at any time.
The phrase at any time uses two words.
Mistake 3: Assuming the words are always interchangeable
They are not always interchangeable.
Compare:
Call me anytime.
and:
I don’t have any time.
Changing one form to the other changes the grammar and meaning.

🌟 Anytime in “Anytime Soon”
The expression anytime soon is normally written as two parts: anytime and soon.
It means at any point in the near future.
Examples:
- Is the package arriving anytime soon?
- I don’t think he’ll return anytime soon.
- Are you planning to move anytime soon?
- Will the website be updated anytime soon?
In these examples, anytime functions as an adverb.
📅 “Any Time You” vs. “Anytime You”
This area can create confusion.
Both forms can appear, but their grammatical structures differ.
Anytime you need help
Call me anytime you need help.
Here, anytime means whenever.
Any time you need help
Any time you need help, call me.
This can also be used, especially when any time means “every time” or “whenever.”
The one-word form is common when anytime clearly functions as an adverb.
🔤 Anytime as an Adverb
An adverb modifies a verb, adjective, or another adverb. Anytime can describe when an action happens.
Examples:
- Call anytime.
- Visit anytime.
- Ask anytime.
- Come anytime.
- Reply anytime.
In each sentence, anytime tells us when the action can happen.
🧩 Any Time as a Noun Phrase
In any time, the word time remains a noun.
Examples:
- Do you have any time?
- I don’t have any time.
- We need any time available.
- She didn’t spend any time there.
The word any acts as a determiner modifying the noun time.
🇺🇸 Anytime in American English
Anytime is widely used in modern American English as an adverb.
For everyday writing, sentences such as:
Feel free to call anytime.
and
You can visit anytime.
are completely natural.
For formal contexts, writers may choose at any time instead.
The two-word form any time remains necessary when time functions as a noun.
📖 Is Anytime One Word or Two Words?
The answer depends on the sentence.
One word:
Call me anytime.
Two words:
I don’t have any time.
Three words:
Call me at any time.
Therefore, there is no single spelling that works in every situation.
🔄 Anytime vs. Any Time vs. At Any Time
This three-way comparison makes the difference easier to understand:
| Expression | Meaning | Example |
|---|---|---|
| Anytime | Whenever | You can call anytime. |
| Any time | Any amount/period of time | I don’t have any time. |
| At any time | Whenever/at any moment | You may leave at any time. |
Remembering these three patterns will solve most usage questions.
💡 Examples From Everyday Situations
At work
You can contact me anytime.

Come over anytime.
Discussing availability
Do you have any time tomorrow?
Talking about free time
I don’t have any time this week.
In a policy

In a text message

These examples show why context matters more than simply memorizing one spelling.
