How long does a treasury bill last?

Treasury bills (T-bills) are short-term government securities that typically have maturities ranging from a few days to one year. Common maturities include 4 weeks, 8 weeks, 13 weeks, 26 weeks, and 52 weeks. At maturity, the face value is paid to the holder, and T-bills do not pay interest but are sold at a discount to their face value.
