Have you ever wondered whether to write “any time” or “anytime”? You’re not alone. Both forms are correct, but they are not always used in exactly the same way. The difference depends mainly on how the word functions in a sentence.
In general, any time is usually used as a noun phrase, especially after prepositions such as at, while anytime is commonly used as an adverb meaning whenever. In modern English, especially American English, anytime is widely accepted in many contexts.
This guide explains any time vs anytime with clear meanings, examples, common mistakes, and simple grammar rules.
Quick Answer
- Any time = A noun phrase meaning “any amount of time” or “whenever,” often used after a preposition.
- Anytime = An adverb meaning “whenever” or “at any time.”
Examples:
- You can call me anytime.
- You can call me at any time.
- Do you have any time to help me?
What Does “Any Time” Mean?
Any time is written as two words when time functions as a noun.
Examples:
- Do you have any time this afternoon?
- I don’t have any time to waste.
- We can meet at any time.
- Have you spent any time studying?
In these sentences, time refers to an amount or period of time.
“At Any Time”
The phrase at any time is always written as two words.
Examples:
- You may leave at any time.
- The situation could change at any time.
- Please contact us at any time.
What Does “Anytime” Mean?
Anytime is usually an adverb meaning whenever or at any time.
Examples:
- Call me anytime.
- You can visit anytime.
- Come over anytime you like.
- I can help anytime.
A useful test is to replace anytime with whenever.
Example:
- Call me anytime.
- Call me whenever.
Both sentences make sense, so anytime is appropriate.
Any Time vs Anytime
| Form | Main Use | Example |
|---|---|---|
| Any time | Noun phrase; often follows a preposition | You can call me at any time. |
| Anytime | Adverb meaning “whenever” | You can call me anytime. |
Both forms can express a similar idea, but their grammatical roles are different.
Examples of “Any Time”
Use any time when time is acting as a noun.
- Do you have any time for a quick meeting?
- I don’t have any time today.
- She didn’t spend any time preparing.
- You can visit us at any time.
- The company may change its policy at any time.
Examples of “Anytime”
Use anytime as an adverb meaning whenever.
- You can call me anytime.
- Come by anytime.
- I am available anytime after lunch.
- You can ask me anytime.
- Visit us anytime you are in town.
The “At” Test
One of the easiest ways to choose between any time and anytime is to look for at.
If the sentence uses at, write:
at any time
Correct:
- You can contact me at any time.
- The rules may change at any time.
Do not write:
- ❌ at anytime
In standard usage, at anytime is generally avoided.
“Anytime” as a Conjunction
In modern informal English, anytime can also introduce a clause meaning whenever.
Examples:
- Anytime you need help, let me know.
- Anytime she visits, we have dinner together.
However, some traditional style guides prefer any time in this position:
- Any time you need help, let me know.
Both forms can be found in modern English, but any time may be preferred in more formal or traditional writing.
Common Mistakes
Writing “At Anytime”
Incorrect:
- ❌ You can call me at anytime.
Correct:
- ✅ You can call me at any time.
- ✅ You can call me anytime.
Using “Anytime” as a Noun
Incorrect:

Here, time is a noun referring to an amount of available time.
American vs British English
Anytime is especially common in American English, particularly as an adverb.
In British English, any time has traditionally been preferred in some contexts, although anytime is also increasingly recognized and used.
For formal writing in either variety, at any time is always a safe and clear choice.

At + any time = two words.
Examples:
