    It probably wouldn't be difficult to change the starting point but,
    I don't know the qualifications offhand. It's not completely arbitrary.

    You might check out other solutions in the Download area here.

    Egbert Zijlema has also done some good work with date handling:

    Tom-

    Whups, I see in the Dateunit.bas the dates should be between
    01-01-1900 and 06-05-2079.

    Uh, what would be involved in making that 01-01-1400?!?

    Reason: I am a family genealogist, and my oldest person is 1504,
    and I hope to go even before that.

    I bet your answer is "no earthly way!," but if it can be done at
    all, I would appreciate knowing how. 100 percent precision
    accuracy is not mandatory- the information I have might be a
    month off.

    I am aware of the Calendar conversion problems, but I try to
    convert all dates to the present calendar system.

    Thank you.

    Tom- well, I will be.... I +do+ have it.

    I guess at some point in time, the Examples directory was
    deleted. I found it by reinstalling PB for dos.

    Thanks.

    See DateUnit.bas in your PBDOS35\Examples directory.

    robert,
    this posting, although initially designed with the windows compiler in mind, still gives everything you need to do what you want.

    started a topic Date/Time differences

    Date/Time differences

    In power basic for Dos, how does one perform date/time
    calculations?

    For example, can I:
    Tyme1$=15:30:45
    Tyme2$=13:22:05

    Tyme3$=Tyme1$-Tyme2$
    How can I get Tyme3$ to equal 01:08:40 ?

    Same deal with dates?
    Dayte1$=20030215 :'format YYYYMMDD
    Dayte2$=20030101
    Dayte3$=Dayte1$-Dayte2$
    I would like for Dayte3$ to equal 14 days in some fashion. Is
    this possible? I have pulled out about a handful of hair to
    make this work.

    This is for employee time clock funtions and calculating
    interest.

    Thank you.

    Robert
