in reply to module for days conversion

I could do this manually by dividing down and using modulus

You may be able to do what you want with Date::Calc. If not, you almost certainly could with Date::Manip::Delta.

When you aren't dealing with specific dates, you run into problems which might not be obvious at first. How many months is 3100 days? Or how many days is 3 months?
