It seems the image you provided isn’t visible here. To help you solve the problem, could you please describe the content of the image in text? For example, if it’s a date calculation problem (like finding days between two dates, determining the day of the week, or leap year questions), share the specific details (dates, context, etc.), and I’ll provide a step-by-step solution.

If you were referring to a common date problem, here’s an example of how to solve one:
Problem: If January 1, 2023, is a Sunday, what day of the week is January 1, 2024?
Solution:
2023 is not a leap year (it’s divisible by 4 but not by 100, but wait—2023 isn’t divisible by 4 at all: 2023 ÷4=505.75). So there are 365 days between Jan1 2023 and Jan1 2024.
365 days = 52 weeks +1 day (since 52×7=364).
Adding 1 day to Sunday gives Monday.

Let me know the exact problem, and I’ll help you solve it!
