Check if the difference between two dates is between limits: EDC/CDMS

+ More

This template checks if after the patient signed informed consent (date1) a visit has taken place (date2) between a day range.

In this template:

date1 and date2 are two date fields in your form. Replace them with your own variable names.
XX and YY are the limits you want to use. Replace them with the number of days you want to check for, e.g. 0 and 14.

var dateDiff = getDateDiff('{date1}','{date2}', 'day');
if(dateDiff > XX || dateDiff < YY){
"Difference between date1 and date2 has to be between XX and YY days,
it's currently " + dateDiff + " days.";
}
