## CONFUSION CLARIFICATIONS

### NUMBER OF DAYS CALCULATION

We should always be having knowledge about the working of a function. Otherwise we may be stuck in a situation where we never know whether the answer is correct or not.

These formulas are doing nothing but playing with the dates.

MS Excel is converting the date to a number first. Number is the number of days after JAN 1 1900.

After converting to number it subtracts to find out the number of days between any two dates.

The same procedure is being followed up in these financial formulas.

These can be done with the simple calculations also but when we have a ready function, we can always take help.
