One more way using jscript embedded into cmd script. Here's the dayAdder.bat that accepts only one argument - the days you want to add to the current date and prints the result:

  @if (@X) == (@Y) @end /* JScript comment 
    @echo off   
    cscript //E:JScript //nologo "%~f0" %*
    exit /b %errorlevel%       
@if (@X)==(@Y) @end JScript comment */

var days=parseInt(WScript.Arguments.Item(0));


Date.prototype.addDays = function(days) {
    var date = new Date(this.valueOf());
    date.setDate(date.getDate() + days);
    return date;
}

var date = new Date();

WScript.Echo(date.addDays(5));
WScript.Echo("Year: " + date.getFullYear());
WScript.Echo("Month: " + date.getMonth());
WScript.Echo("DayOfTeWEek: " + date.getDay());

examaple:

E:\scripts>dayAdder.bat 7
Sun Nov 8 16:27:48 UTC+0200 2020
Year: 2020
Month: 10
DayOfTeWEek: 2
DayOfTheMonth: 3

You can modify it in way that will be suitable for you.
