# Week

## 1 Week = 7 Days

A week has seven days:

 Day of the Week In 3 Letters Monday Mon Tuesday Tue Wednesday Wed Thursday Thu Friday Fri Saturday Sat Sunday Sun

But it doesn't have to be Monday to Sunday ...

... a week can be any period of 7 days.

Example: Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday and Monday together make one week.

It could also go from one time to the same time 7 days later:

Example: From Midday on Thursday to Midday the next Thursday is also one week.
