Up to date and up-to-date are both correct in American English. The difference is mainly grammatical: the hyphenated form normally works as a compound modifier directly before a noun, while the open form commonly appears after a verb or in other positions.
For example:
- The website is up to date.
- We need an up-to-date website.
Both sentences describe something current. The hyphens change because the phrase has a different role in the sentence.
Quick Answer
Use up-to-date when the phrase directly modifies a noun:
We need an up-to-date report.
Use up to date when the phrase follows a verb or functions as an open phrase:
The report is up to date.
The choice is therefore not about one spelling being correct and the other being wrong. Both are standard forms; sentence structure determines the usual hyphenation.
Why People Confuse Them
The confusion is understandable because the meaning stays very close.
Both forms can describe something that is current, modern, or based on the latest available information. The visible difference is only the two hyphens, but those hyphens signal that the three words are working together as a compound modifier.
Compare:
- an up-to-date calendar
- The calendar is up to date.
The same basic idea appears in both sentences. In the first, the phrase comes directly before and modifies “calendar.” In the second, it follows the linking verb “is” and describes the calendar.
Key Differences At A Glance
| Context | Best Choice | Why |
|---|---|---|
| Directly before a noun | up-to-date | The words form a compound modifier |
| After a linking verb | up to date | The phrase describes the subject |
| After “keep” | up to date | The phrase functions openly after the verb |
| After “bring” | up to date | The phrase follows the verb in an established expression |
| Before “information” | up-to-date | The phrase directly modifies the noun |

Meaning and Usage Difference
The core meaning is essentially the same: something is current or reflects the latest available information.
Up to date is common when describing a state or condition:
The customer records are up to date.
Please keep me up to date on the schedule.
We brought the team up to date on the changes.
Up-to-date is common when the phrase directly modifies a noun:
Please review the up-to-date customer records.
She used an up-to-date schedule.
The office needs up-to-date information.
The important point is that the hyphenated form is not a different concept. It is the same expression functioning as a compound modifier.
Tone, Context, and Formality
Neither form is inherently more formal. Both can appear in professional, academic, technical, and everyday American English.
At work, you might write:
Please make sure the client records are up to date.
Or:
Please send the up-to-date client records.
In school or academic writing:
The information in the paper should be up to date.
Or:
Use up-to-date research when discussing current developments.
The context does not determine the hyphenation by itself. Sentence structure does.
Which One Should You Use?
Look at what comes immediately after the phrase.
If the phrase directly modifies a noun, use up-to-date:
an up-to-date schedule
up-to-date records
an up-to-date resume
If the phrase follows a verb, the open form is normally appropriate:
The schedule is up to date.
Her resume is up to date.
Please keep your profile up to date.
A useful editing habit is to identify whether the phrase is acting as a compound modifier before a noun. If it is, use the hyphenated form.
When One Choice Sounds Wrong
Some sentences look awkward because the hyphenation does not match the phrase’s grammatical position.
For example:
We need an up to date report.
In this sentence, the phrase directly modifies “report,” so the standard form is:
We need an up-to-date report.
Now consider:
The report is up-to-date.
In standard American style, the open form is normally preferred here:
The report is up to date.
The same distinction applies to many similar sentences. The hyphen is useful when the words need to work together before a noun as one descriptive unit.
Common Mistakes (and Quick Fixes)
Mistake: Missing the hyphens before a noun
an up to date calendar
Fix:
an up-to-date calendar
Mistake: Adding hyphens after a linking verb
The calendar is up-to-date.
Usual fix:
The calendar is up to date.
Mistake: Assuming one form is always correct
Neither form should be used everywhere. Choose according to its grammatical position.
Mistake: Treating the hyphenated form as a different meaning
The hyphenation usually changes the structure, not the basic idea. “An up-to-date file” and “the file is up to date” can describe the same current file.
Everyday Examples
Here are natural examples for common US-English situations:
- Please make sure the contact list is up to date.
- We need an up-to-date contact list before the meeting.
- Her account information is up to date.
- The bank requested an up-to-date statement.
- I try to stay up to date on industry news.
- The company publishes up-to-date information on its website.
- Bring me up to date before the presentation starts.
- The employee handbook contains up-to-date policies.
- Is your calendar up to date?
- We need an up-to-date calendar for the new semester.
Notice that the meaning remains closely connected. The main change is how the phrase fits into the sentence.
Dictionary-Style Word Details
Verb
- up to date: Not commonly used as a verb. It can follow verbs such as “keep,” “bring,” and “stay.”
- up-to-date: Not a verb. It functions as a descriptive compound form.

Noun
- up to date: Not commonly used as a noun in standard American English.
- up-to-date: Not normally used as a standalone noun.

Synonyms
- up to date: Closest plain alternatives include current, informed, and fully current, depending on the sentence.
- up-to-date: Closest plain alternatives include current, modern, latest, or recent, depending on the intended meaning.

Word History
The expression has a long-established history in English. Dictionary sources trace up-to-date to the 19th century, with Collins giving an origin range of 1865–70. The modern distinction between the hyphenated compound modifier and the open phrase reflects established English usage rather than a recent invention.

- up to date
- up-to-date information
- up-to-date records
- keep up to date

FAQs
Is “up to date” correct in American English?
Yes. “Up to date” is standard when the phrase follows a verb or works as a phrase rather than directly modifying a following noun. For example, “The records are up to date” is correct American English.
Is “up-to-date” also correct?
Yes. “Up-to-date” is correct when the three words work together as a compound modifier before a noun. For example, “an up-to-date record” uses the hyphenated form to show that the words modify “record” as one unit.
Are “up to date” and “up-to-date” interchangeable?
Not in every sentence. They carry essentially the same idea, but their grammatical placement differs. Compare “The website is up to date” with “an up-to-date website.” The first is open; the second is hyphenated.
Should I hyphenate “up to date” after “is”?
Usually no. In a sentence such as “The schedule is up to date,” the phrase follows the linking verb and describes the schedule. Standard American usage generally leaves the phrase open in this position.
What about “keep up to date”?
Write “keep up to date” without hyphens when the phrase follows “keep,” as in “Please keep me up to date on the project.” If it directly modifies a noun, use the hyphenated form instead: “up-to-date project information.”
Which form should I use before a noun?
Use “up-to-date” before the noun it directly modifies. Write “up-to-date information,” “an up-to-date calendar,” or “up-to-date records.” This hyphenation makes the compound modifier easy to read and avoids treating the words as separate units.
Conclusion
Up to date and up-to-date are both correct in US English. The difference is primarily grammatical.
Use up-to-date when the phrase directly modifies a noun:
an up-to-date report
Use up to date when it follows a verb or appears as an open phrase:
The report is up to date.
Remember the sentence structure rather than trying to memorize one form as universally correct. Once you identify the phrase’s role, the hyphenation becomes much easier to choose.
