Why is day convention important?
A day-count convention measures how interest accrues on investments like bonds, notes, mortgages, and loans over time. The calculation is important to traders of various bonds because, when a bond is sold, the seller is entitled to a portion of the coupon payment. The day-count convention determines precisely how much.
How do you use day count convention?
To apply an actual day count convention, we need to know the exact number of actual days, or nights, in the period. This is driven by the days in each month. Because of the varying lengths of calendar months, adding up the days in three consecutive months results in periods of 89, 90, 91 or 92 days.
Why is the day count convention for a financial instrument important?

Why is 360 days used to calculate interest?
When using the Actual/360 method, the annual interest rate is divided by 360 to get the daily interest rate and then multiplied by the days in the month. This creates a larger dollar amount in interest payments because dividing the annual rate by 360 creates a larger daily rate then dividing it by 365.

How do you find the exact real interest rate?
real interest rate ≈ nominal interest rate − inflation rate. To find the real interest rate, we take the nominal interest rate and subtract the inflation rate. For example, if a loan has a 12 percent interest rate and the inflation rate is 8 percent, then the real return on that loan is 4 percent.
