I used to have an app. like this one on my Palm, but now I have an Ipaq.
No one seems to have written an app. like this yet for the PocketPC.
So, here it is.

If you have pocket PC, and dates is important for you,it must be on your PDA. Usening it very simple, very easy and very useful. And it is free... Thank you very much.

Handy prog for calculating dates. There is actually one from Biohazard Software... but always nice to have more than one choice. Would like to see it auto-calculate when a date is changed rather than having to press CALC. Perhaps add a button between the up/down arrows instead of having to double click dates? Otherwise, no complaints. Simple and works well.
