date calculation with week and day count

Hi,

To get the number of days between today and the conception date (fieldname2), you simply should use the equation:

(function(){
var days = ROUND((new Date()).valueOf()/86400000);
return ABS(days-fieldname2);
})()

To get the number of weeks you can divide the result by 7

(function(){
var days = ROUND((new Date()).valueOf()/86400000);
return FLOOR(ABS(days-fieldname2)/7);
})()

To get the number of weeks and days:

(function(){
var days = ROUND((new Date()).valueOf()/86400000);
return FLOOR(ABS(days-fieldname2)/7)+' weeks and '+(ABS(days-fieldname2)%7)+' days';
})()

Best regards.
