Home Weekday Before If today is Friday, 2 days before

If today is Friday, what day was it 2 days before?

Answer: Wednesday

Weekdays repeat every 7 days. So we only need the remainder after dividing 2 by 7, then move backward that many days from Friday.

Quick rule:
remainder = 2 mod 7 = 2
move backward 2 day(s) from Friday
Wednesday

Detailed Math (Step-by-Step)

We show the whole operation clearly (modulo 7).

Step 1: Find the remainder

Since weekdays repeat every 7 days: days mod 7 tells us how many steps to move backward.

Days 2
Divide by 7 0 remainder 2
Remainder 2
Meaning: Jump whole weeks first (they don’t change the weekday), then move the remainder days backward.

Step 2: Move backward 2 day(s)

Start at Friday and count backward 2 step(s).

Step Weekday
0Friday (start)
1Thursday
2Wednesday (result)
Final: Friday − 2 days = Wednesday
