[edit] Why?

Someone wrote a comment in the article asking why the US used it's particular 360 day calendar variant, and what the advantages of it were. I removed it because it was unencyclopedic, but the answer would be a good thing to put in the article, if anyone knows.--82.45.163.18 17:25, 9 October 2006 (UTC)

[edit] Leap Years

How is 29 February handled in each of the systems?

[edit] Quoted Formulae Are Wrong

The formulae given are simply incorrect. The correct ones are as follows:

  • 30E/360
    • If either the first date or last date of the accrual period falls on the 31st of a month, that date will be changed to the 30th.
    • If the last day of the accrual period falls on the last day of February, the month of February will not be extended to a 30-day month and the actual number of days in February will be used.
  • 30US/360
    • If the last date of the accrual period is the last day of February and the first date of the period is the last day of February, then the last date of the period will be changed to the 30th.
    • If the first date of the accrual period falls on the 31st of a month or is the last day of February, that date will be changed to the 30th of the month.
    • If the first date of the accrual period falls on the 30th of a month after applying (2) above, and the last date of the period falls on the 31st of a month, the last date will be changed to the 30th of the month.

Out of courtesy to other posters, I will leave it for a few days to get any feedback before rewording the text.

I can also give a citation for the Excel bug. TerryE (talk) 04:06, 2 January 2008 (UTC)
