Why does Project change duration by 1 day

[Ameesh Oza]

I have a problem that Microsoft Project changes the duration by -1 day. The
start and finish dates are being updated using VB macros by a 3rd party
application. If original duration was 3 days it becomes 2 days. The
application is not changing the duration in any way - only start and finish
dates. The dates coming from the application are the same as the original
planned start/finish dates. The only difference is that application marks
task as 100% complete. What gives??

thanks

Hi,

The application doesn't do anything but what you ask for in your code or in
the options.
As for the 100% done, I suspect you enter an actual finish date
As for the "loss" of a duration day, display a date format including date
and time, and verify Tools, Options, Calendar, whether default finish time
hasn't been set at start of day.
Or with your VB, only enter dates including time of day.

Good point Jan.
I've seen this when I forgot to set the finish time at 17:00.
If you use a date only (say 19 sept 2004) then project interprets that as
00:00 and you lose a day.
