This is budgeting related so I'm going with a 4-4-5 calendar

This is for work and will be used by alot of people so I want this to be simple and easy to use for people with varying (or lacking) technical skills.

I have 4 monetary values that need to be tracked so I plane to create the spreadsheet to cover an entire year's worth of data and because there will be one for each weekday resulting in 260 entries in a non-leap year. So I want to give the user the option to view the spreadsheet by week/month/year and default to the current month while giving the same options for the graph.

If someone could point me in the right direction, I can take it from there.

Thanks in advance.
