Week’s
We must use an apostrophe to indicate ownership. This is called the possessive form. Examples of the possessive form include “the dog’s ears” and “the wives’ tales.”
If we write “week” in the singular possessive form (belonging to one week only), we can spell it as week’s.
Examples of Sentences with Week’s
- Julie is going to go to the hairdresser in a week’s time.
- Mary has to give a week’s notice if she wants to leave work.
- The birthday celebration is in one week’s time.
- The newspaper covers this week’s weather report.
- I won this week’s draw.
- Last week’s news was shocking.
Week’s Used as a Contraction
Week’s can also be used as a contraction, though it’s quite informal and much less likely. A contraction is a shortened form of a word. For example, isn’t is short for “is not” and what‘s is short for “what is.
Week’s can be short for “week is” or “week has.”
For example,
- “This week’s (=week has) been a whirlwind adventure.
- “This week’s (=week is) flying.”
- “This week’s (=week is) not going to be fun.”
- “I am glad this week’s (=week is) over.”
Weeks’
If we are writing “week” in the plural possessive (belonging to more than one week), we spell it as weeks’.
Examples of Sentences with Weeks’

- Mary has to give six weeks’ notice if she wants to go on holiday.
