# If Today Is Tuesday, what was the day before 18 days

If today is tuesday,what was the date before 18 days ago ?
## How do we solve it ?

A week has 7 days " Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday ".

18 / 7 = 2 ( Remainder = 4)

So you can say that before multiples of 7 days, the day will repeat itself as tuesday.

Hence before 14 days Tuesday would occur again.

So we calculate before the remainder (4) , the answer is Friday.

**Simple Logic** = And whatever the remainder obtained is, deduct that to the day.
