16 January 2023 was a Monday.
To find the day on 12 January 2024, we need to calculate the number of days between these two dates.
From 16 January 2023 to 16 January 2024 is exactly 1 year.
2023 is not a leap year (not divisible by 4), so it has 365 days.
365=52×7+1
This means 365 days = 52 weeks + 1 day.
Therefore, 16 January 2024 falls 1 day after Monday, which is Tuesday.
From 16 January 2024 to 12 January 2024 is 4 days backward.
Going back 4 days from Tuesday:
- Tuesday → Monday (1 day back)
- Monday → Sunday (2 days back)
- Sunday → Saturday (3 days back)
- Saturday → Friday (4 days back)
Therefore, 12 January 2024 was a Friday.
The correct answer is Option 3: Friday.
