\[ \text{Total days} = 365 + 30 = 395 \]
Since a week has 7 days, we divide:
\[ 395 \div 7 = 56 \text{ weeks with a remainder of } 3 \]
The remainder is 3, meaning we move 3 days forward from Tuesday:
Thus, 8th Dec 2017 falls on a Friday.
If it was a Friday on 15th September 2023, then what will be the day on 20th September 2024?
