Task: Fix Week Calculation in Menu.js

Objective: Update the week calculation logic in the Menu.js file to ensure that it correctly calculates the current week number, constrained between 0-3. This change should account for edge cases such as leap years, transitions between months, and varying days in the week.

Requirements:

1. Valid Week Range: The calculation must always return a week number in the range of 0 to 3 (inclusive), which means that any calculated week value outside this range should be handled appropriately (e.g., wrapping or capping the value).
2. Edge Cases:
   • End of Month: Ensure the logic handles the transition between months (e.g., when a month ends mid-week).
   • Leap Year: Handle February in leap years properly (with 29 days) when calculating weeks.
   • Week Transition: Address situations where the first or last days of a month affect the current week calculation.

Suggested Fix:

1. Refactor the existing week calculation logic.
2. Ensure that it wraps or resets the week value when it exceeds 3 (i.e., Week 4 wraps back to Week 0).
3. Add unit tests or manual test cases to validate against edge cases like:
   • Weeks that span across months.
   • Days around February 28th and 29th (in leap years).
   • Ensuring that calculations on different days return the correct week value.

@Mohd-FaiZ-Jr I have added a new logic to calculate the week number. Please review the changes.
