Answer: There is no specific date set to pay the US National debt. The National debt is being paid on any given day of any given year. The "debt" is to those people and governments that purchase US Bonds and such. When you as an individual purchase a US Treasury Bond you are effectively loaning the US government money. That bond "matures" after a period of time and is worth the stated value. You may redeem the bond at any time before it matures but you will pay a penalty. This penalty serves a very important purpose. It helps assure the government that the purchaser will most likely hold the bond until its maturity date thereby allowing the government a reasonable amount of assurance as to how much it will need to pay out on any given day based on the bonds that are maturing. Foreign governments purchase bonds also but these are with different terms and the amounts of money are staggering but they to have a stated interest rate and maturity date. Shockwaves shoot through the stockmarket when large amounts of bonds ar due to mature and it appears the holder will simply cash them in and not reinvest in more bonds. The potential is America could possibly not have the cash in reserve to make such a payment.
