Calculation

Support
1

Hi All,
I have a variable that collects LMNP - this is a date field
I want to automatically calculate the weeks of amenorrhea whose formula is
1) add 7 days to the day of the date
2) for months in the date that are above 9 add number 3
3) for months that are below or equal to 9 subtract 3 from the
date.
someone help me calculate the amenorrhea

Hi Ayoub,

Date calculations are notoriously tricky. Read the threads at
https://groups.google.com/forum/#!searchin/opendatakit/date$20add, then try
each step you've described and let the list know how far you get.

Thanks,

Yaw
