You are getting mixed up betweent T-Bills and Bonds. T-Bills can be bought for as short as a 7 day maturity. Or you can buy 30-60-90-180-360 day T-Bills. Bonds are usually longer maturity dates. Please go to treasurydirect.gov,for a government site it is excellent,and it will answer all you questions and turn you into a auction pro. Once you figure it out and open an account, I suggest you buy a 7 day T-Bill for a $1,000.00 to get your feet wet, once you figure it out you will never go back.
