Created Unassigned: minjday and maxjday [10178]

I am using SharePoint FormFields . And I have one sharepoint datetime column, but there i need to set the mindate property of the control . Can I use Spservice in any way to achieve that? If we check in developer tools the control is rendered like below. Can anyone suggest what is this "minjday" and "maxjday" here.? And how we can set that?



<a onclick="clickDatePicker("ctl00_m_g_9bd9765c_837c_4ca8_9460_414013562630_ff81_ctl00_ctl00_DateTimeField_DateTimeFieldDate", "\u002fsites\u002ftreasury\u002f_layouts\u002fiframe.aspx?&cal=1&lcid=1033&langid=1033&tz=-05:00:00.0009535&ww=0111110&fdow=0&fwoy=0&hj=0&swn=False&
minjday=109207&maxjday=2666269&date=", "", event);return false;" href="#">
