Error 8: Calendar

a This is the case for the 31st of March, May, August, October, and December,
plus August 29 (except in a leap year) and 30. For example, there is no Septem-
ber 31, so March 31 has no corresponding coupon date 6 months earlier.
To correct this problem for all maturity dates except August 29 and 30, add one
day to both the settlement date and the maturity date in your calculations. For
instance, if a bond were purchased on June 1, 2004 (the settlement date) with a
maturity date of December 31, 2005, you should change the dates to June 2,
2003 and January 1, 2006 for your calculations.
For August 29 and 30, there is no calculator solution that gives the correct
answer.
