The following formulas are used in the above calculations:

$d={\displaystyle \frac{\mathrm{Year}}{\mathrm{Days}}}\times {\displaystyle \frac{(F-P)}{F}}$
$P=\text{Purchase price}$
$F=\text{Face value}$
$d=\text{Discount Rate}$
$\mathrm{Days}=\text{Number of days to maturity}$
$\mathrm{Year}=360=\text{Constant number of days in a year}$

As you can see from the above formula, the discount rate represents the annualized rate of the discount you get off the face value when you purchase a T-Bill.
