Answer 1

This is a copy of AlwaysHelpings answer, yet with a different approach of disabling the last three days of a month.

 var dateToday = new Date(); $("#datepicker").datepicker({ beforeShowDay: noLastThreeDays, minDate: dateToday }); function noLastThreeDays(date){ //REM: Last day of month var tLastDayOfMonth = new Date(date.getFullYear(), date.getMonth() + 1, 0); //REM: Date of the passed date var tDate = date.getDate(); //REM: Lock the last three days of the month if( tDate === tLastDayOfMonth.getDate() || tDate === tLastDayOfMonth.getDate()-1 || tDate === tLastDayOfMonth.getDate()-2 ){ return [false, "closed", "Sorry We are closed"] } else{ return [true, "", ""] } }

Answer 2

This solution (also derived from AlwaysHelping's deleted answer) determines the last day of the current month manually, and compares it to the current date.

To add further customizations to the datepicker object, add them as key/value pairs after beforeShowDay: noLastThreeDays (eg: to hide all past days, use minDate: 0 as shown.)

Check out the datepicker documentation for more info.

 $("#datepicker").datepicker({ beforeShowDay: noLastThreeDays, //minDate: 0 }); function noLastThreeDays(date){ const dd = date.getDate(), mo = date.getMonth(), yr = date.getFullYear(), thirtyDayMonths = [3,5,8,10], // Apr, Jun, Sep, Nov isLeapYear = (yr) => (yr % 100 === 0)? (yr % 400 === 0): (yr % 4 === 0); // Last date of month let last = 31; if(thirtyDayMonths.includes(mo)){ last = 30; } if(mo === 1){ last = isLeapYear(yr)? 29: 28; } // Output to datepicker const result = (dd <= last - 3)? [true, "", ""]: [false, "closed", "Sorry We are closed"]; return result; }
