What Are Days and Weeks?


A day has 24 hours. A day has passed after the hour hand on a clock with revolving hands has gone two rounds. A day starts at 00:00 am, which is at midnight.

The word day has two meanings. It can mean the time between every midnight, which is how we have used it until now. It can also mean the time from sunrise to sunset, which is opposite to night.

When we put seven days after each other, you get a new unit of time, which is known as a week. Every day of the week has its own name.

Seven days of 24 hours make a week

The seven days of the week are:

  • The first day of the week is: MONDAY

  • The second day of the week is: TUESDAY

  • The third day of the week is: WEDNESDAY

  • The fourth day of the week is: THURSDAY

  • The fifth day of the week is: FRIDAY

  • The sixth day of the week is: SATURDAY

  • The seventh day of the week is: SUNDAY

Monday is the first day of the week. We call the five first days weekdays. Weekdays are Monday, Tuesday, Wednesday, Thursday and Friday. The two last days, Saturday and Sunday, we call the weekend.

The weekend actually begins when you are done with school on Friday. So, we can say that the weekend lasts from when you’re finished with school on Friday until you go to bed on Sunday.

The week divided into weekdays and weekend

Think About This

It is useful to learn all of the days. They can be easier to remember if you find yourself a melody you can sing the days to:

Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday

Example 1

How many days are there in three weeks?

3 weeks = (3 7) days = 21 days

There are 21 days in three weeks.

Example 2

How many weeks and days are there in 18 days?

18 days = (18 ÷ 7) days = 2.57 weeks  (0.57 7) days = 4 days

There are 2 weeks and 4 days in 18 days.
