Timetable and Salary Calculator

I need an Excel spreadsheet to manage a weekly timetable that sums up to a complete month. The spreadsheet should calculate total working hours and days, and provide the total salary based on both hourly wage and varying daily rates.

Requirements:
- Input for hourly wage and daily rates
- Varying daily rates for different days
- Summation of weeks to a complete month
- Total working hours and days calculation
- Final output of total salary

Ideal skills:
