8th April 2019 is a Friday. What day was 3rd February of the same year?

3rd February was a Sunday.

Step-by-step explanation:

8th April is a Friday, so subtract 7 to get the date of the Friday before. Repeat this process:

8-7=1st April

February has 28 days in this year, because 2019 isn't a leap year. So:

1-7=22nd February

22-7=15th February

15-7=8th February

8-7=1st February

All these dates are Fridays. So if the 1st February is a Friday, the 2nd February is a Saturday, and the 3rd February is a Sunday.
