hi all,

could someone please help me with the following:
in reading 64 p370 of the curriculum, the day count convention is explained. it is said that for coupon bearing treasury securities, the day count convention used is to determine the actual number of days.
however, in reading 65, page 406, when calculating the yield on treasury bills they do the following:

- first: they assume 360 days in a year
- and then, I thought they would at least consistently use 30 days per month BUT, then they do use the actual days.

Why didn't they use 365 days in a year? I'm totally confused about what to use when, and afraid I will lose some points on such a stupid thing.

Did anyone find an overview of what to use when?

Thanks a lot!

Deborah
