I always have a hard time remembering when to use 360 and when to use 365. I’d hate to lose points on something so simple.

anyone have any tips for how they keep it straight?

#2

I think the only time u use 360 is when LIBOR is involved

#3

libor, FRA (because they are based on libor), T-Bill - 360 days

everything else 365
