Days between dates

From Fred Kaufman

CompuServe ID: [72560,36]

Calculate the number of days between two dates depending on the calendar method (1 = real, 2 = 365, 3 = 30/360)

{Calendar|

!Days between dates!

if(S(today),cdate-

today,0*(Date1+Date2)+

if(s(Date2),Date

(Date1,#ofDays)-Date2,ddays

(Date1,Date2,Calendar)-

#ofDays ))=0

!calendar:1=real:2=365;3=

30/360!}

This gives you an example that you could use in another equation. On the 100/200LX you can also perform date arithmetic directly with the Date Calcs function (press [CTRL]-[D] in HP Calc. Its easier than keying in and checking and equation if all you need is the number of days between dates.
