With the help of lodash, I used _.isEqual and _.isEqual

see: https://lodash.com/docs/4.17.15#isEqual https://lodash.com/docs/4.17.15#isEqual

I also added schedules3 in case.

const schedules = {
Friday : [
 {isOpen: true},
 {morningOpen: "08:30"},
 {morningClose: "12:00"},
 {afternoonOpen: "18:30"},
 {afternoonClose: "18:30"}
],
Monday : [
 {isOpen: true},
 {morningOpen: "08:30"},
 {morningClose: "12:00"},
 {afternoonOpen: "18:30"},
 {afternoonClose: "18:30"}
],
Saturday : [
 {isOpen: true},
 {morningOpen: "08:30"},
 {morningClose: "12:00"},
 {afternoonOpen: "20:30"},
 {afternoonClose: "20:30"}
],
Sunday : [
 {isOpen: true},
 {morningOpen: "08:30"},
 {morningClose: "12:00"},
 {afternoonOpen: "20:30"},
 {afternoonClose: "20:30"}
],
Thursday : [
 {isOpen: true},
 {morningOpen: "08:30"},
 {morningClose: "12:00"},
 {afternoonOpen: "18:30"},
 {afternoonClose: "18:30"}
],
Tuesday : [
 {isOpen: true},
 {morningOpen: "08:30"},
 {morningClose: "12:00"},
 {afternoonOpen: "18:30"},
 {afternoonClose: "18:30"}
],
Wednesday : [
 {isOpen: true},
 {morningOpen: "08:30"},
 {morningClose: "12:00"},
 {afternoonOpen: "18:30"},
 {afternoonClose: "18:30"}
]
};

var schedules1= schedules.Friday;
var schedules2= {};
var schedules3= {};

var schedules1_days = [];
var schedules2_days = [];
var schedules3_days = [];

for (const [key, currentObj] of Object.entries(schedules)) {
    if(_.isEqual(currentObj,schedules1)){
    schedules1_days.push(key);
  }else if(_.isEqual(currentObj,schedules2)){
    schedules2_days.push(key);
  }else if(_.isEqual(currentObj,schedules3)){
    schedules3_days.push(key);
  }else{
    if(_.isEmpty(schedules2)){
      schedules2 = currentObj;
      schedules2_days.push(key);
    }else if(_.isEmpty(schedules3)){
      schedules3 = currentObj;
      schedules3_days.push(key);
    }
    
  }
}

schedules1 = {...schedules1, days: schedules1_days};
schedules2 = {...schedules2, days: schedules2_days};
if(!_.isEmpty(schedules3)){
      schedules3 = {...schedules3, days: schedules3_days};
}


console.log(schedules1);
console.log(schedules2);
console.log(schedules3);
