What happens if you change the start date after changing the end date? Does your calc then work correctly?https://www.infopathdev.com:443/forums/thread/120437.aspxMon, 18 Feb 2019 15:29:34 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:120437SG1230https://www.infopathdev.com:443/forums/thread/120437.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=41&PostID=120437<p>&nbsp;Hello All,</p><p>Need your support to help me&nbsp;write a formula to get workdays between two dates in InfoPath 2013. I have used below mentioned thread&nbsp;and wrote formula in my form.</p><p><a href="https://www.meartechnology.co.uk/blog/2016/09/16/infopath-calculate-business-days-between-2-dates-including-leap-year/">https://www.meartechnology.co.uk/blog/2016/09/16/infopath-calculate-business-days-between-2-dates-including-leap-year/</a></p><p>This works fine, till the end date - year is changed.
