Hi

I am in the middle of a Biorhythm VB program and am wondering how to use Date Picker

Currently I am working on a phase of 18 days, so I assume MOD18 will come into it somewhere (you can tell I am a beginner)

My Date Picker seems to go back to Jan 1st 1601

On that day, the 18 day cycle is on day 16 of the 18 day cycle.

So what I need to know is - if I use Date Picker to choose a date of, say, March 9th 1967 - how can I get it to calculate what day of the 18 day cycle March 9th 1967 falls on (still assuming that Jan 1st 1601 is day 16 of the 18 day cycle)

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,0,1,2...........

AND is there a site which simply explains how to use DP ?

Thanks for looking

Mike
