Var vv = '2017-02-07 ';
Var vNowDate = moment (new moment (vv ). format ("YYYY-MM-DD "));//. add ('month', 0 ). add ('days ',-1 );
Var vWeekOfDay = moment (vNowDate). format ("E"); // calculate the week number of this week
Var vWeekOfDays = 7-vWeekOfDay-1;
Var vStartDate = moment (vNowDate). add ('days ', vWeekOfDays );
Var vEndDate = moment (vNowDate). add ('days ',-vWeekOfDay );
Var vStartDateNew = moment (vStartDate). add ('days ', 7 * $ scope. gWeeks );
Var vEndDateNew = moment (vEndDate). add ('days ',-(7 * $ scope. gWeeks ));
// Var vYearAndWeek = moment (vStartDate). format ("YYYY") + '-' + moment (vStartDate). format ("WW ");
SearchMajorChanges (vStartDateNew, vEndDateNew );
