We are asked to find the day of the week for 1st January 2023, given that 1st January 2022 was a Saturday.
- 2022 is not a leap year, so it has 365 days.
- Dividing 365 by 7, we get a remainder of 1, meaning that 1st January 2023 is 1 day ahead of 1st January 2022.
Since 1st January 2022 was a Saturday, 1 day ahead would be Sunday.
Therefore, 1st January 2023 will be a Sunday.
