Please see attached form (download &gt; right click &gt; open in design mode) and check if you are able to add the logic to you form&#39;s formula.<br /><br />Hope this helps.<br /><br />Regards,</p>Date Calculation - Need to add a year and minus a dayhttps://www.infopathdev.com:443/forums/thread/103388.aspxFri, 24 Jul 2015 01:04:32 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:103388novaguy0https://www.infopathdev.com:443/forums/thread/103388.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=41&PostID=103388I have a date picker field - based on the date selected, I need to show another date field on the same form which is basically - Add one year minus a day. AddDays does not cater for leap years. See attached screenshot of the code, works fine except if date chosen is 03/31/2015, the value calculated is 02/28/2016 - Should be 02/29/2016 as its a leap year. PLEASE HELP. THANKS a Million all INFOPATH gurus out there.
