Tomorrow’s or Tomorrows: Which Spelling Is Correct?

Tomorrow’s and tomorrows are both correct words, but they have different meanings.

Tomorrow’s is used to show possession or to mean “tomorrow is,” while tomorrows is the plural form of “tomorrow” and means several future days.

The apostrophe is important because it changes the grammatical role of the word. This confusion often happens because English uses apostrophes for possession and contractions, while plural words usually do not need them.

In this guide, you will learn the difference between tomorrow’s and tomorrows, when to use each form, common mistakes, British and American usage, and simple examples for everyday and formal writing.

Quick Answer

The quick answer is simple:

Tomorrow’s = possession or a contraction.
Tomorrows = the plural of tomorrow.

Tomorrow’s for possession

Use tomorrow’s when something is connected to or associated with tomorrow.

Tomorrow’s meeting starts at 10 a.m.

I checked tomorrow’s weather forecast.

Tomorrow’s schedule is very busy.

Here, tomorrow’s means something related to tomorrow.

Tomorrow’s as a contraction

Tomorrow’s can also mean “tomorrow is.”

Tomorrow’s going to be busy.

This means:

Tomorrow is going to be busy.

Another example:

Tomorrow’s the big day.

This means:

Tomorrow is the big day.

Tomorrows for more than one future day

Use tomorrows when you mean several future days.

We cannot predict all our tomorrows.

Our choices today can create better tomorrows.

This plural form is correct, but it is much less common in everyday English. Dictionaries list tomorrows as the plural form of tomorrow.

The Origin of Tomorrow’s or Tomorrows

The word tomorrow has a long history in English. Merriam-Webster traces it to Middle English to morgen and Old English tō morgen, meaning roughly “on the morning to come.” It has been used as an adverb since the 13th century and as a noun since the 14th century.

Over time, tomorrow became the standard modern English word for the day after today.

The forms tomorrow’s and tomorrows developed from normal English grammar rules.

Tomorrow’s adds ’s to show possession:

tomorrow + ’s = tomorrow’s

It can also be a contraction:

tomorrow is → tomorrow’s

Tomorrows adds s to make the noun plural:

tomorrow + s = tomorrows

The key difference is the apostrophe. An apostrophe can show possession or missing letters in a contraction. It does not normally make a word plural.

British English vs American English Spelling

There is no major spelling difference between British and American English for tomorrow’s or tomorrows.

Both varieties use:

Meaning	British English	American English
Possession	tomorrow’s	tomorrow’s
“Tomorrow is”	tomorrow’s	tomorrow’s
Plural	tomorrows	tomorrows
Next day	tomorrow	tomorrow

For example, both British and American writers can say:

Tomorrow’s meeting starts at nine.

They can also use:

We should prepare for the tomorrows ahead.

The difference is therefore not a British-versus-American spelling issue. It is mainly a grammar and meaning issue.

Cambridge also uses tomorrow’s for things connected with the following day, such as “tomorrow’s meeting.”

Which Spelling Should You Use?

Choose the form based on what you mean.

For US English

Use tomorrow’s for possession or a contraction.

Tomorrow’s presentation starts at noon.

Tomorrow’s going to be difficult.

Use tomorrows only when you truly mean several future days.

We hope for better tomorrows.

For UK and Commonwealth English

The same rule applies.

Tomorrow’s exam is important.

Tomorrow’s going to be warmer.

We must think about our tomorrows.

For a global audience

If you are writing for an international audience, tomorrow’s will be far more common and useful.

If you mean a specific future day, use tomorrow or tomorrow’s.

If you mean several future days, use tomorrows.

A simple rule is:

One future day or something linked to tomorrow → tomorrow’s.

Several future days → tomorrows.

Common Mistakes with Tomorrow’s or Tomorrows

Mistake 1: Writing “tomorrows meeting”

Incorrect:

Tomorrows meeting starts at 9 a.m.

Correct:

Tomorrow’s meeting starts at 9 a.m.

The meeting is connected with tomorrow, so the possessive form needs an apostrophe.

Mistake 2: Thinking the apostrophe makes a plural

An apostrophe does not make tomorrow plural.

tomorrow = one future day
tomorrows = more than one future day
tomorrow’s = possessive or contraction

Mistake 3: Using “tomorrows” for one event

Incorrect:

Tomorrows class has been cancelled.

Correct:

Tomorrow’s class has been cancelled.

The class is associated with one specific tomorrow.

Mistake 4: Forgetting the contraction

Tomorrow’s going to be sunny.

This is correct because tomorrow’s means tomorrow is.

You can test it by replacing tomorrow’s with tomorrow is:

Tomorrow is going to be sunny.

The sentence still works.

Mistake 5: Adding an apostrophe to a simple time reference

When tomorrow simply tells you when something happens, no apostrophe is needed.

Correct:

I will call you tomorrow.

Not:

I will call you tomorrow’s.

Tomorrow’s or Tomorrows – Google Trends & Usage Data

Search interest for tomorrow’s and tomorrows is not equal. The possessive form is much more useful in normal writing because people often need to describe something connected with the next day, such as tomorrow’s meeting, tomorrow’s weather, tomorrow’s exam, or tomorrow’s schedule.

The plural tomorrows is a real word, but it is uncommon in everyday communication. It appears more naturally in literary, motivational, poetic, and philosophical writing. Collins lists tomorrows as the plural form and gives examples involving the idea of future days.

Searches around this topic usually come from people asking which form is correct in a sentence. The main practical issue is therefore apostrophe use rather than a difference between British and American spelling.

Because search trends change over time, exact Google Trends numbers should be checked for a selected country and date range rather than treated as permanent figures.
